Top 10 Best Kensington Trackball in 2026 Compared

The following comparison places every Kensington trackball side by side, highlighting the differences in ball size, connection method, scroll mechanism, programmability, and ergonomic design that matter most when choosing a model.

1. Kensington Expert Wireless Trackball Mouse – Best Overall Kensington Trackball

4.2Editor scoreCheck price on Amazon

Kensington Expert Wireless Trackball Mouse

Large 55mm ball

Diamond Eye optical tracking

Bluetooth LE and 2.4GHz

Four customizable buttons

The Kensington Expert Wireless Trackball Mouse is the most versatile all-around model in this guide, combining a large 55mm ball, precise optical tracking, a mechanical scroll ring, and flexible wireless connectivity. Its 4.2 rating reflects a balanced feature set, although the product's strongest appeal comes from the generous ball and uncluttered combination of wireless options.

Pros

• Large ball supports broad control
• Flexible wireless connection options
• Useful customization and scroll ring
• Detachable wrist rest included

Cons

• Wireless mode compatibility varies
• Windows ARM support unavailable

The large ball makes slower, deliberate pointer movements possible and gives users more physical surface to work with than the 32mm, 34mm, or 40mm balls found elsewhere in the range. The patented scroll ring is useful for long documents, spreadsheets, and web pages, while the four-button design can be personalized with KensingtonKonnect software. A detachable wrist rest adds support without forcing the user to keep a fixed accessory attached.

The Expert supports Bluetooth LE and a 2.4GHz USB dongle, making it suitable for systems where one method is more convenient than the other. Auto-sleep and adjustable power settings help conserve battery use, although Bluetooth performance is strongest on relatively recent Windows and macOS systems. It is compatible with Windows, macOS 10.14 or later, and ChromeOS 44 or later, but Windows ARM-based computers are not currently supported.

This is a strong recommendation for users who want a large ball, wireless freedom, mechanical scrolling, and meaningful button customization without moving to a thumb-operated design. It may not be ideal if you need Windows ARM support or want a rechargeable USB-C battery, but its general-purpose design suits office work, creative software, web browsing, and multi-computer setups.

Large-Ball Control and Comfort

The 55mm ball gives the Expert a noticeably different feel from compact Orbit models. Its larger surface supports smoother, less hurried movement, while the detachable wrist rest can help maintain a supported hand position during long work sessions.

Flexible Wireless Workflows

Bluetooth LE and the included 2.4GHz dongle give users two practical ways to connect. The auto-sleep function and configurable power settings help limit unnecessary energy use, making the model well suited to desks that alternate between wired and wireless accessories.

2. Kensington SlimBlade Pro Wireless Trackball – Best Premium Kensington Trackball

4.1Editor scoreCheck price on Amazon

Kensington SlimBlade Pro Wireless Trackball

55mm dual-sensor ball

Bluetooth and 2.4GHz

Wired charging connection

Eight programmable button sets

The Kensington SlimBlade Pro Wireless Trackball is the premium option in this lineup, pairing a low-profile body with a rechargeable battery and three connection paths. Its 4.1 rating does not stand out numerically, but the supplied specifications show a particularly extensive feature set aimed at users who want one device to handle several kinds of work.

Pros

• Three connection options
• Rechargeable four-month battery
• Extensive programmable controls
• Low-profile ambidextrous design

Cons

• Windows ARM support unavailable
• Software compatibility needs checking

We may earn a commission when you buy through this link, at no additional cost to you.

Its large 55mm ball is monitored by dual sensors for accurate tracking, responsive scrolling, and consistent cursor control. The low-profile design takes up less desk space than a conventional mouse and is intended to reduce the amount of arm and wrist movement required during extended use. Importantly, its ambidextrous shape is designed to suit both right- and left-handed users.

Connection flexibility is the SlimBlade Pro's defining strength. It supports Bluetooth, 2.4GHz wireless through a USB-A receiver, and a wired USB-C connection. A USB-C-to-USB-A adapter and a 1.5-meter charging cable are included, while the rechargeable battery is stated to last four months from a single charge. KensingtonKonnect also expands eight sets of programmable buttons, offering considerably deeper customization than most competing entries here.

The trade-off is that this feature density may be unnecessary for a user who simply wants a comfortable mouse replacement. Software installation and compatibility should be considered, particularly because Windows ARM computers are not currently supported. Even so, professionals managing complex applications, multiple button commands, and varied connectivity needs have a reason to look beyond the standard wireless models.

Rechargeable Battery Convenience

The USB-C rechargeable design removes the need to replace disposable batteries. Its stated four-month runtime provides a long interval between charges, while the wired mode can also support users who prefer a continuously connected setup.

Deep Button Customization

Eight sets of programmable buttons make this model suitable for productivity software and repeated workflows. Users can assign a broad selection of program functions through KensingtonKonnect, although Windows ARM systems should be checked for current support before purchase.

3. Kensington Orbit Trackball Mouse with Scroll Ring (K72337US), 4 1/2X5 1/2X2"

4.3Editor scoreCheck price on Amazon

Kensington Orbit Trackball with Scroll Ring

Medium 40mm ball

Optical tracking technology

Mechanical scroll ring

Two customizable buttons

The Kensington Orbit Trackball Mouse with Scroll Ring offers one of the strongest balances of comfort, precision, and useful controls in the guide. Its 4.3 rating is among the higher figures in the list, and the combination of optical tracking, a 40mm ball, and a mechanical scroll ring covers the essentials without requiring wireless setup or a rechargeable battery.

Pros

• Well-rounded feature selection
• Precise optical tracking
• Supportive detachable wrist rest
• Works with either hand

Cons

• Wired USB connection only
• Only two programmable buttons

We may earn a commission when you buy through this link, at no additional cost to you.

The 40mm ball is formed as an absolute hard sphere to support controlled cursor movement, while optical technology helps the system respond accurately. The scroll ring allows quick movement through pages and documents and feels more deliberate than clicking a conventional wheel. The detachable wrist rest softly supports the hand during longer sessions, and the ambidextrous layout broadens its appeal.

KensingtonKonnect allows users to assign program functions to the two buttons and adjust cursor and scrolling speeds. That is meaningful customization for a relatively straightforward model, although it falls short of the SlimBlade Pro's extensive button sets. ChromeOS users can access basic HID functions, but they cannot customize the device through KensingtonWorks.

The main compromise is wired connectivity, which means this is not the right choice for someone who wants a clean, cable-free desk or frequent switching among several computers. For a single desk and a user who values a mechanical scroll ring, reliable optical tracking, and a removable wrist rest, however, this Orbit is a compelling and economical choice.

A Useful Mechanical Scroll Ring

The scroll ring provides quick, tactile access to vertical scrolling without taking up the space of a separate mouse wheel. It is particularly useful in long documents, research pages, and spreadsheets where continuous vertical movement is common.

Balanced Ergonomic Design

The medium ball balances maneuverability with a surface large enough for deliberate control. A detachable wrist rest and ambidextrous shape make the model accessible to a broad range of users without forcing a particular hand orientation.

4. Kensington Orbit Trackball Mouse (K64327F), Silver/Black

4.2Editor scoreCheck price on Amazon

Kensington Orbit Trackball Mouse

Medium 40mm ball

Internal red optical sensor

Wired USB connectivity

Two programmable buttons

The Kensington Orbit Trackball Mouse is a straightforward wired option for users who want the core benefits of a trackball without wireless complexity. Its 4.2 rating reflects a dependable, familiar design, while the compact silver-and-black body uses considerably less desk space than a full-sized mouse.

Pros

• No batteries required
• Compact and space efficient
• Simple reliable USB setup
• Compatible with major systems

Cons

• No scroll ring included
• Only two programmable buttons

We may earn a commission when you buy through this link, at no additional cost to you.

Internal red optics track the movement of the medium 40mm ball and deliver accurate pointer positioning. Unlike the scroll-ring version of the Orbit, this model does not include a ring or wheel for vertical scrolling. Users who need vertical movement will therefore depend on standard clicking and scrolling methods available through the system.

The wired USB connection requires no batteries and offers a straightforward installation path. KensingtonKonnect lets users assign program functions to the two buttons and adjust cursor speed, providing useful control without adding extensive hardware. The design is ambidextrous, and it is compatible with Windows, macOS 10.8 or later, and ChromeOS 44 or later.

This is a sensible choice for a fixed workstation where cable management is easy and simplicity matters. Its limitations are clear: no scroll ring, no wireless operation, and only two programmable buttons. Those restrictions make it less versatile than the newer Orbit Wireless, but they also make it a focused option for users who primarily need accurate cursor control.

Reliable Wired Simplicity

A fixed USB connection eliminates charging routines, wireless pairing, and battery concerns. For a permanent desk, that simplicity can make the Orbit easier to maintain than a rechargeable multi-device alternative.

Compact Footprint and Storage

The small body occupies less space than a conventional mouse and is easy to reposition. Its ambidextrous form also means either hand can control it, making the model practical for shared or changing workstations.

5. Kensington Wired SlimBlade Trackball Mouse (K72327U), Black

4.3Editor scoreCheck price on Amazon

Kensington Wired SlimBlade Trackball Mouse

Low-profile SlimBlade shape

Laser tracking technology

Wired USB connection

Programmable button support

The Kensington Wired SlimBlade Trackball Mouse combines a low-profile body with laser tracking and a 4.3 rating, placing it among the best-rated products in this guide. Its appeal lies in a clean, space-saving design that reduces arm and wrist movement without introducing wireless controls or a large battery.

Pros

• Excellent 4.3 user rating
• Low-profile ergonomic footprint
• Smooth laser-based tracking
• Suitable for either hand

Cons

• No wireless connectivity
• Button details are limited

We may earn a commission when you buy through this link, at no additional cost to you.

The silver metallic finish gives the mouse a more refined appearance than many basic trackballs, while the low-profile shape helps conserve desk space. Its laser tracking system provides precise cursor control, and the ambidextrous construction allows use with either hand. These qualities make it a natural fit for users who spend long periods navigating documents, creative applications, or complex desktop software.

KensingtonWorks provides button customization, so the mouse is not limited to basic left and right clicking. Nevertheless, the supplied product information provides fewer details about the number and range of programmable controls than the Expert, SlimBlade Pro, or vertical TB675. The wired configuration also eliminates wireless pairing and battery management altogether.

For a dedicated workstation, the Wired SlimBlade is an attractive balance of styling, compact ergonomics, and precise control. Users shopping across multiple devices or wanting a rechargeable model should look farther up the list, but those who value a stable wired pointer and understated design will find this model straightforward and capable.

Low-Profile Workspace Design

The slim body leaves more room for keyboards, notes, and other desk essentials. Its low profile also keeps the user's hand closer to the work surface, which can make a trackball feel more integrated with a compact office setup.

Precise Laser Tracking

Laser tracking supports accurate cursor movement across applications. Combined with the ambidextrous layout, it offers a versatile alternative to a traditional mouse while preserving familiar two-button interaction.

6. Kensington Orbit Wireless Trackball with Scroll Ring – Space Gray (K72675WW),Black/Grey

4.2Editor scoreCheck price on Amazon

Kensington Orbit Wireless Trackball

40mm precision ball

Bluetooth and 2.4GHz

Four selectable DPI levels

Detachable wrist rest

The Kensington Orbit Wireless Trackball with Scroll Ring is a particularly complete option for users who want wireless freedom without giving up a mechanical scroll ring. Its 4.2 rating and broad feature set make it a strong middle-ground choice between the budget wired Orbit and more advanced premium models.

Pros

• Excellent wireless flexibility
• Useful four-level DPI control
• Mechanical scroll ring
• Secure 128-bit AES encryption

Cons

• Battery life is not specified
• Wrist rest may add bulk

We may earn a commission when you buy through this link, at no additional cost to you.

The device supports 2.4GHz and Bluetooth 3.0 plus LE, allowing users to choose between a dedicated receiver and direct wireless connectivity. The 2.4GHz option includes 128-bit AES government-grade encryption. A hard-surfaced 40mm ball delivers accurate optical tracking, while the scroll ring handles vertical movement through pages and long documents.

Four DPI settings—400, 800, 1,200, and 1,600—make it possible to move between precise editing and faster navigation. KensingtonKonnect adds further control through programmable functions, shortcuts, cursor-speed adjustment, and scrolling-speed adjustment. A detachable wrist rest provides soft support, and the ambidextrous design works for both left- and right-handed users.

The model is compatible with Mac and PC systems, making it a practical choice for mixed environments. Battery runtime is not stated in the supplied information, so users who work for extended periods away from power should confirm expectations. Otherwise, its connectivity options, precision controls, and comfortable layout create one of the most versatile configurations in the Orbit family.

Control for Different Tasks

The four DPI levels make it easy to tune pointer speed for both detailed work and everyday browsing. KensingtonKonnect expands that control by supporting shortcuts, button assignments, and separate cursor and scrolling adjustments.

Two Wireless Connection Methods

Bluetooth and 2.4GHz support different working styles, from a receiver-based setup to a direct connection. The encrypted 2.4GHz option also adds an extra layer of security for users who work in shared or sensitive environments.

7. Kensington Orbit Wireless Trackball Mouse with Touch Scroll Ring (K72352US),Black

4.2Editor scoreCheck price on Amazon

Kensington Orbit Wireless Touch Scroll

Compact 32mm ball

Bluetooth LE and USB receiver

Touch-based scroll ring

Plug-and-play wireless setup

The Kensington Orbit Wireless Trackball Mouse with Touch Scroll Ring is designed for users with small to average-sized hands and limited desk space. Its 4.2 rating reflects a capable design, and the combination of a 32mm ball, compact body, and touch-based scroll interface differentiates it from the larger Orbit models.

Pros

• Very compact footprint
• No drivers required
• Flexible wireless connections
• Suitable for smaller hands

Cons

• Smaller ball limits surface
• Touch scrolling is less tactile

We may earn a commission when you buy through this link, at no additional cost to you.

The smaller ball allows users to move the pointer with less fingertip travel and can be comfortable for people who find a 40mm or 55mm surface too large. The touch scroll ring permits movement through documents and web pages without a conventional protruding wheel, preserving the product's compact appearance and keeping the overall design uncluttered.

Wireless connectivity works through Bluetooth LE or a USB nano receiver, and the device supports plug-and-play use without drivers. KensingtonKonnect supports a customized productivity experience, although the supplied information does not describe the extent of button programming. The ambidextrous design can be used with either hand.

This Orbit is best for someone who values a small footprint more than maximal ball size or extensive programmability. The touch interface may also feel less tactile than a physical scroll ring. Nevertheless, it offers an easy wireless setup, a compact shape, and a practical control surface for common office tasks.

Made for Compact Desks

The 32mm ball and small body minimize the space needed to operate the device. That makes the model a practical option for compact work areas where a full-size mouse would occupy valuable room.

Simple Wireless Connection

Bluetooth LE and the USB nano receiver provide two familiar connection paths. With no driver installation required, the mouse can offer a quick transition from unpacked box to everyday productivity.

8. Kensington Orbit Optical Trackball Mouse, USB 2.0, Left/Right Hand Use, Black/Silver

4.0Editor scoreCheck price on Amazon

Kensington Orbit Optical Trackball Mouse

Medium 40mm ball

Optical tracking technology

Wired USB 2.0 connection

Compact ambidextrous design

The Kensington Orbit Optical Trackball Mouse is a simple, dependable option for users who want accurate pointer control and a compact footprint. Its 4.0 rating places it toward the lower end of this guide's numerical range, but the supplied specifications cover the essential trackball experience without unnecessary complexity.

Pros

• Accurate optical tracking
• Perfectly spherical ball
• Compact and space efficient
• Easy wired installation

Cons

• No wireless connectivity
• No customization details listed

We may earn a commission when you buy through this link, at no additional cost to you.

Optical tracking technology supports precise cursor control, and the medium 40mm ball is engineered as a perfect sphere for consistent movement. The ambidextrous design works for left- and right-handed users, while the compact body takes up less desk space than a traditional mouse. These characteristics make it especially suitable for limited workspaces.

Installation is straightforward through its wired USB 2.0 connection. There are no wireless pairing steps, battery requirements, or charging routines to manage. The supplied information focuses on core operation and does not describe the model in the same level of detail as newer products with extensive software customization.

The Orbit Optical is best for someone who values a straightforward, space-conscious pointer over wireless flexibility or advanced button mapping. Users who regularly scroll long documents should also consider a model with a dedicated scroll ring. For basic navigation and standard productivity tasks, however, its spherical 40mm ball and optical system provide a solid foundation.

Consistent Spherical Tracking

The 40mm ball is designed as a perfect sphere to support even movement. Optical tracking then helps translate that physical movement into accurate cursor positioning across the screen.

Reliable Plug-and-Play Operation

Wired USB 2.0 connectivity avoids wireless setup and battery management. It is a straightforward configuration for a permanent computer station where consistent access to power and USB is already available.

9. Kensington TB675 Wireless Vertical Trackball Mouse, Ergonomic Design, Rechargeable – Black (K72171WWMY)

3.8Editor scoreCheck price on Amazon

Kensington TB675 Wireless Vertical Trackball

34mm thumb-operated ball

60-degree vertical tilt

Four-device wireless switching

Nine programmable buttons

The Kensington TB675 Wireless Vertical Trackball Mouse is the guide's most distinctive alternative to conventional finger-operated trackballs. Its 3.8 rating is the lowest among these products, but the 60-degree vertical design, rechargeable construction, and four-device support give it a compelling feature set for users who prefer a thumb-operated approach.

Pros

• Natural vertical hand position
• Connects with up to four devices
• Extensive nine-button customization
• Tilt-enabled four-direction scroll wheel

Cons

• Lowest rating in the guide
• Thumb operation requires adaptation

We may earn a commission when you buy through this link, at no additional cost to you.

The contoured body places the hand at a 60-degree angle, supporting more natural wrist and thumb positioning. A 34mm ball is operated with the thumb rather than the index finger, while a high-precision optical sensor and four DPI settings provide accurate control. The design is stated to suit average-sized hands, so users with very small or very large hands may want to consider fit carefully.

Connectivity is unusually flexible. The device can connect to up to four computers through a 2.4GHz dongle, dual Bluetooth, and a wired USB-C connection, with a built-in selector for switching devices. The 2.4GHz option includes 128-bit AES encryption. A metal four-direction scroll wheel adds vertical and side-to-side navigation for spreadsheets, timelines, and wide documents.

Nine programmable buttons provide more controls than any other model in the guide, and KensingtonKonnect can assign shortcuts or macros, including to the two side buttons. The trade-offs are the lowest rating, a learning curve for users accustomed to finger-operated balls, and the possibility that the vertical form will not suit every hand. It is a strong recommendation for multi-device power users seeking an explicitly ergonomic vertical layout.

Thumb-Operated Vertical Ergonomics

The 60-degree tilt positions the thumb naturally above the ball and encourages a less twisted wrist. This vertical arrangement distinguishes the TB675 from the flatter, index-finger-operated Kensington models reviewed elsewhere.

Multi-Device Productivity

A device selector and support for four connected systems streamline switching among computers. Dual Bluetooth, 2.4GHz, and wired USB-C make the mouse suitable for workflows that move between a desk, laptop, and portable setup.

Kensington Slimblade Trackball

SlimBlade trackball design

Low-profile low-profile body

Compact desk footprint

Wired product configuration

The Kensington Slimblade Trackball has the highest numerical rating in the guide at 4.5, making it a notable option for buyers who want a compact, dedicated trackball. The supplied listing identifies it as the Kensington Slimblade Trackball, model K72327US, but provides considerably less descriptive information than the other products.

Pros

• Highest rating in the guide
• Space-saving SlimBlade design
• Low-profile ergonomic shape
• Simple central ball control

Cons

• Sparse supplied product details
• Connection options are not detailed

We may earn a commission when you buy through this link, at no additional cost to you.

Based on its model identification and the broader SlimBlade design reflected in the guide, the product offers a low-profile trackball format that occupies less desk space than a conventional mouse. Central ball operation avoids the sweeping movements required to reposition a standard mouse, supporting a more stationary working style.

The product's strongest documented advantage is its strong user rating. Its compact form is also attractive for users building an uncluttered workstation or working in a limited space. However, the supplied data does not detail its exact tracking method, connection type, software functions, or button configuration, so buyers should verify those details on the current listing.

It is a reasonable recommendation for a user attracted to the Slimblade format who values a high-rated, space-efficient model. Those who need a clearly documented scroll ring, wireless options, battery life, or extensive programmability will find more explicit information in the Wired SlimBlade, Expert, or SlimBlade Pro. Confirm the final specifications before ordering.

A Space-Saving Trackball Format

The low-profile Slimblade form keeps the mouse footprint compact while centralizing pointer control around the ball. It is well suited to users who want to reduce repeated arm movement without dedicating substantial desk space.

Strong User Reception

Its 4.5 rating is the highest in the guide, suggesting favorable user reception. Because the supplied specification is limited, that rating should be considered alongside confirmation of connection, button, and software details on the current product page.

Buying Guide – How to Choose the Best Kensington Trackball

The most suitable Kensington trackball depends on how you move your hand, how much desk space you have, how often you switch computers, and whether you prioritize a large ball, a mechanical scroll ring, wireless freedom, or extensive button customization.

Ball Size and Control Style

Kensington's range includes 32mm, 34mm, 40mm, and 55mm balls, and each size creates a different control experience. The large 55mm balls in the Expert and SlimBlade Pro provide a broad surface for slower, more deliberate movement. The 40mm Orbit balls provide a middle ground and are especially common in the range. The compact 32mm Orbit is designed for small to average-sized hands, while the TB675 uses a 34mm ball operated by the thumb rather than the index finger.

Finger-Operated Versus Thumb-Operated

Most Kensington trackballs are controlled with the index finger, keeping the hand relatively flat over a ball positioned near the keyboard. The TB675 instead adopts a 60-degree vertical shape and uses the thumb. That layout can support more natural wrist positioning, but users accustomed to index-finger movement may need time to adjust. Hand size is also important because the vertical model is stated to suit average-sized hands.

Scroll Controls

Scrolling behavior varies substantially across the line. The Expert, wired Orbit with Scroll Ring, and Orbit Wireless use a mechanical scroll ring, while the smaller Orbit Wireless with Touch Scroll Ring uses touch interaction. The basic wired Orbit, Orbit Optical, and Slimblade listings do not highlight a dedicated ring in the supplied specifications. Mechanical rings provide tactile vertical movement, whereas touch scrolling preserves a flatter, more compact profile.

Connection and Battery Needs

Wired models such as the Orbit and SlimBlade are straightforward choices for permanent desks, while wireless products allow cleaner workspaces and greater mobility. Bluetooth and 2.4GHz receivers support different computer setups. The Expert uses Bluetooth LE or a 2.4GHz dongle, the Orbit Wireless supports Bluetooth and 2.4GHz, and the TB675 can manage up to four devices. The SlimBlade Pro adds a wired option and uses a rechargeable USB-C battery.

Programmable Buttons and Software

KensingtonKonnect and KensingtonWorks add value by allowing users to assign functions, shortcuts, and speed adjustments to compatible models. The Expert supports a customizable four-button design, the SlimBlade Pro provides eight sets of programmable buttons, and the TB675 offers nine programmable buttons. The basic Orbit models provide two customizable buttons. Confirm that your computer's operating system supports the relevant software, since Windows ARM-based systems are not currently supported for the Expert or SlimBlade Pro.

Desk Space and Wrist Support

A trackball remains stationary while the ball rotates, so every model uses less operating space than a traditional mouse. The Expert, wired Orbit with Scroll Ring, and Orbit Wireless include detachable wrist rests for users who want additional support. The slim Expert, SlimBlade, and SlimBlade Pro shapes prioritize a low profile, while the TB675 deliberately uses more vertical space to achieve its thumb-operated angle.

Hand Size and Ambidextrous Use

Most products in the guide are ambidextrous, allowing either hand to control the ball. That broadens their suitability for shared desks and users who do not want to force one hand into an unfamiliar posture. The compact touch-scroll Orbit is specifically designed for small to average-sized hands, while the TB675 is stated to fit average-sized hands. The 55mm Expert and SlimBlade Pro offer a larger surface that may suit people who prefer finer control.

Operating System Compatibility

The supplied specifications list broad support for Windows, macOS, and ChromeOS, but compatibility details vary. The Expert is compatible with Windows, macOS 10.14 or later, and ChromeOS 44 or later, while the basic Orbit supports macOS 10.8 or later. ChromeOS users can use basic HID functions on that Orbit but cannot customize it through KensingtonWorks. The Expert and SlimBlade Pro currently exclude Windows ARM-based computers.

How to Use and Care for Your Kensington Trackball

Begin by placing the trackball where your hand can reach the ball without raising your arm or twisting your wrist. Keep the device on a clean, level surface and use only the ball itself to move the pointer. Avoid pushing or dragging the entire unit, because moving the housing rather than rotating the ball can produce unintended cursor jumps and reduce the smoothness of the control.

For a wired model, connect the USB cable and allow the computer to recognize the device. For a wireless model, choose Bluetooth or the supplied 2.4GHz receiver and follow the pairing instructions for the compatible operating system. Install KensingtonKonnect or KensingtonWorks when you want to adjust pointer speed, scrolling behavior, button assignments, shortcuts, or macros. Configuration should be performed on a supported system.

Keep the ball and sensor area free from dust, crumbs, hair, and sticky residue. Turn off or disconnect a wireless trackball before cleaning it, and use a soft dry or lightly dampened cloth rather than immersing the unit. The compact ball on the touch-scroll model requires particular care because the touch ring may not react as expected when covered by residue. Check battery levels or charging status regularly, and use the stated USB-C charging method for the SlimBlade Pro.

Frequently Asked Questions

Is a Kensington trackball better than a regular mouse?

A Kensington trackball can suit users who want to keep their hand in one position and avoid repeatedly moving a mouse across the desk. It may also be useful in confined spaces because the device itself stays stationary. Personal preference matters, so users with sensitive wrists or limited mobility should consider comfort and learning time before making a switch.

Which Kensington trackball has the largest ball?

The Expert Wireless Trackball Mouse and SlimBlade Pro Wireless Trackball each use a 55mm ball, the largest size represented in this guide. The large surface supports controlled pointer movement and can feel more precise than the smaller 32mm, 34mm, and 40mm alternatives. Hand size and preferred movement style should still guide the final choice.

What is the difference between a scroll ring and a touch scroll ring?

A scroll ring is rotated physically to move through a document, while a touch scroll ring responds to a touch gesture along its surface. The mechanical ring can offer more tactile feedback, whereas the touch design helps maintain a flatter and more compact shape. The Expert and two larger Orbit models use mechanical rings, while the compact Orbit Wireless Touch Scroll model uses touch interaction.

Can Kensington trackballs connect to more than one computer?

The TB675 is explicitly designed to connect with up to four devices through dual Bluetooth, a 2.4GHz dongle, and a wired USB-C connection, with a built-in selector for switching. Other wireless models also support 2.4GHz and Bluetooth, but their supplied information does not claim the same four-device simultaneous workflow. Check the individual product specifications when multi-computer use is essential.

Do Kensington trackballs require batteries?

Wired models do not require batteries because they draw power through their USB connection. Wireless models use their own power source, while the SlimBlade Pro uses a rechargeable USB-C battery stated to last four months per charge. Battery life is not specified in the supplied details for every wireless Orbit, so users with intensive mobile schedules should confirm it on the current listing.

Is a thumb-operated trackball comfortable?

A thumb-operated trackball can feel more natural for people who prefer a vertical hand position, but it requires adaptation from conventional mouse movement. The Kensington TB675 uses a 60-degree vertical layout and a 34mm thumb-operated ball, and it is stated to suit average-sized hands. Users who dislike vertical mice or have very small or very large hands may prefer a flat finger-operated model.

Can I customize the buttons on a Kensington trackball?

Compatible models can be customized through KensingtonKonnect or KensingtonWorks. The options vary by product, ranging from two-button Orbit models to the eight programmable button sets of the SlimBlade Pro and nine buttons on the TB675. Windows ARM systems are not currently supported by the Expert or SlimBlade Pro, and the basic wired Orbit's ChromeOS customization is also limited.

How do I clean a Kensington trackball?

Disconnect or switch off the device, then remove loose debris from around the ball and sensor without forcing anything into narrow openings. Use a soft cloth for the housing, and avoid excessive moisture because electronic components are inside. Regular gentle cleaning helps maintain smooth rolling and reliable optical tracking.

Final Thoughts on Choosing the Best Kensington Trackball

The Kensington Expert Wireless Trackball Mouse is the strongest all-around recommendation for its 55mm ball, scroll ring, detachable wrist rest, and Bluetooth plus 2.4GHz connectivity. The SlimBlade Pro is the premium alternative for rechargeable power, three connection options, and extensive programmability, while the wired Orbit with Scroll Ring delivers a balanced and economical core trackball experience.

Prioritize the fit that matches your work: choose a large 55mm ball for broad control, a 40mm Orbit for a conventional middle ground, or the 32mm compact model for smaller hands and limited space. Consider the TB675 if a vertical 60-degree layout and four-device workflow appeal to you, and pay close attention to scroll style, software support, and operating-system compatibility.

Before purchasing, verify the current listing because prices, ratings, software support, and availability can change.
