Top 10 Best Kensington Trackball in 2026 Compared

This side-by-side comparison highlights the differences in tracking size, connectivity, button customization, wrist support, and intended workflow across all ten Kensington trackballs.

1. Expert Wireless Trackball Mouse – Best Overall Kensington Trackball

4.2Editor scoreCheck price on Amazon

Expert Wireless Trackball Mouse

55mm precision tracking ball

Bluetooth and 2.4GHz wireless

Four customizable buttons

Detachable ergonomic wrist rest

The Kensington Expert Wireless Trackball Mouse combines a large 55mm ball, wireless freedom, a detachable wrist rest, and a four-button customizable design. Its 4.2 customer rating reflects a balanced package that suits office work, creative applications, and everyday navigation without attempting to specialize in only one workflow.

Pros

• Large, precise ball
• Flexible wireless connectivity
• Useful button customization
• Removable wrist support
• Broad system compatibility

Cons

The large ball is the model's most important feature. Its hard surface and Diamond Eye optical tracking are intended to provide precise cursor control, while the patented scroll ring offers a familiar way to move through long documents. Bluetooth LE and the supplied 2.4GHz USB dongle allow you to choose between a clean desk and a dependable receiver-based connection.

KensingtonKonnect expands the experience by supporting customizable buttons, cursor speed, and scroll speed. Auto-sleep and adjustable power settings help conserve energy, while compatibility with Windows, recent macOS versions, and Chrome OS broadens its usefulness. The wrist rest detaches when desk space or a different hand position becomes more important.

There are some practical limitations. Windows ARM-based computers are not currently supported, and the most useful control adjustments depend on the software. Nevertheless, the combination of ball size, scrolling hardware, wireless options, and removable support makes this an excellent general recommendation for someone who wants a capable Kensington trackball without moving to the specialized vertical design.

Precise Control With a Large Ball

The 55mm ball provides more surface area than the compact Orbit models, which can make slow positioning and fine adjustments feel more controlled. Optical tracking supports smooth movement while the scroll ring handles rapid vertical navigation.

Wireless Options for Flexible Workspaces

Use Bluetooth LE when pairing directly with a compatible computer, or select the 2.4GHz dongle when a consistent receiver connection is preferable. Auto-sleep helps limit unnecessary battery use during inactive periods.

2. SlimBlade Pro Wireless Trackball – Most Feature-Rich Wireless Model

4.1Editor scoreCheck price on Amazon

SlimBlade Pro Wireless Trackball

55mm dual-sensor ball

Bluetooth, 2.4GHz, wired

Eight programmable button sets

Four-month rechargeable battery

The SlimBlade Pro Wireless Trackball is the most programmable and connectivity-rich model in this guide. Its 4.1 rating reflects a sophisticated device that combines a 55mm ball, rechargeable battery, wired operation, Bluetooth, 2.4GHz wireless, and eight sets of programmable buttons.

Pros

• Three connection methods
• Rechargeable four-month battery
• Extensive button programming
• Low-profile ambidextrous shape
• Large dual-sensor ball

Cons

• Windows ARM unsupported
• Control changes require software

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

Dual sensors track the large ball accurately and responsively. The low-profile body takes up less desk space than a traditional mouse and is shaped for both right- and left-handed users. Its USB-C charging connection and claimed four months of battery life make it convenient for extended work sessions away from a constant power source.

The standout strength is programmability. KensingtonKonnect allows users to assign a wide range of program functions to eight sets of buttons, which is particularly useful for creative tools, office applications, and command-heavy workflows. A 2.4GHz receiver is included with a USB-A-to-USB-C adapter, while a USB-C charging cable is also included for wired use.

This level of functionality comes with trade-offs. It is a more specialized device than the basic Orbit models, and customization depends on KensingtonKonnect. Windows ARM support is also absent at present. For a buyer who values maximum controls and connection flexibility, however, the SlimBlade Pro offers the most ambitious specification set here.

Programmable Controls for Specialized Work

Eight button sets allow you to maintain different configurations for separate applications. This is a meaningful advantage for users who switch between editing, productivity, and navigation software throughout the day.

One Device Across Connection Modes

Bluetooth, 2.4GHz, and wired operation cover different working patterns. The rechargeable design removes routine battery replacement while preserving the freedom to travel between a desk, meeting room, or second computer.

3. Orbit Trackball with Scroll Ring – Balanced Wired Comfort

4.3Editor scoreCheck price on Amazon

Orbit Trackball with Scroll Ring

40mm spherical tracking ball

Wired USB connectivity

Two programmable buttons

Detachable cushioned wrist rest

The Orbit Trackball Mouse with Scroll Ring is a balanced, approachable wired model with a 4.3 customer rating. Its 40mm ball, optical tracking, scroll ring, and detachable wrist rest deliver the core trackball experience without the more complex feature set found in premium models.

Pros

• Strong customer rating
• Precise optical tracking
• Dedicated scroll ring
• Comfortable removable wrist rest
• Works with both hands

Cons

• Only two programmable buttons
• Wired design limits portability

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

The absolute spherical hard-surface ball is designed for accurate tracking and controlled movement. Its scroll ring provides a tactile alternative to rotating a conventional mouse wheel, while the wrist rest softly cushions the hand during extended computer work. The ambidextrous design broadens its appeal to both right- and left-handed users.

KensingtonKonnect allows the two buttons to be assigned to program functions, and cursor and scrolling speeds can be adjusted. ChromeOS users receive basic HID functions, although full device customization is not available. The wired connection avoids battery management and is a straightforward choice for a fixed workstation.

Its limitations are modest but real: there are only two programmable buttons, and it cannot operate wirelessly. If you want a dependable wired trackball with a physical scroll ring and comfortable wrist support, this Orbit model remains one of the strongest all-around choices in the Kensington range.

Tactile Scrolling for Long Documents

The dedicated scroll ring makes vertical movement easy to perform without changing grip. It is particularly useful in long web pages, reports, spreadsheets, and reference documents where repeated wheel rotation can become tiring.

Simple Fixed-Workstation Setup

A wired USB connection keeps setup uncomplicated and removes charging or battery replacement from the equation. The detachable wrist rest also allows the user to reposition or remove it as the desk layout changes.

4. Orbit Trackball Mouse – Best Value for Everyday Computing

4.2Editor scoreCheck price on Amazon

Orbit Trackball Mouse

40mm optical tracking ball

Wired USB connectivity

Two programmable buttons

Compact battery-free design

The basic Kensington Orbit Trackball Mouse is a straightforward choice for buyers who want the core benefits of trackball operation without wireless hardware, rechargeable batteries, or a dense button layout. Its 4.2 rating indicates solid reception across a practical range of everyday uses.

Pros

• Straightforward USB setup
• No batteries required
• Compact desk footprint
• Ambidextrous operation
• Adjustable cursor speeds

Cons

• No scroll ring
• Limited button customization

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

Internal red optics track the medium 40mm ball and support controlled cursor movement. The compact body occupies less desk space than a mouse, while the ambidextrous layout works equally well with either hand. The wired USB connection is reliable, simple to install, and avoids batteries entirely.

KensingtonKonnect can assign program functions to the two buttons and adjust cursor speed. Compatibility covers Windows, macOS 10.8 and later, and Chrome OS 44 and later. It is a sensible product for browsing, document work, and basic productivity where a mouse wheel remains sufficient.

The absence of a scroll ring is the main compromise, particularly for users who regularly work with long documents. With only two customizable buttons, it also falls short for shortcut-heavy professionals. Even so, it offers a compact, battery-free introduction to Kensington trackballs and remains the best-value selection in this guide.

A Frugal Fixed-Computer Choice

Because it draws power through USB, this Orbit model avoids battery purchases and charging routines. It is particularly convenient for a permanent office or home-computer setup.

Small Footprint, Familiar Operation

The 40mm ball and compact housing are easier to accommodate than larger desktop devices. The result is a familiar pointer experience with less need to move the device around.

5. Wired SlimBlade Trackball – Low-Profile Ergonomic Alternative

4.3Editor scoreCheck price on Amazon

Wired SlimBlade Trackball

Low-profile sloped housing

Wired USB connectivity

Laser tracking technology

Ambidextrous low-profile design

The Wired SlimBlade Trackball Mouse offers a sleek, low-profile alternative to conventional mouse designs. Its 4.3 rating, ambidextrous shape, laser tracking, and compact desktop profile make it especially attractive for users who want a slim input device without a battery.

Pros

• High customer rating
• Space-saving low profile
• Precise laser tracking
• Comfortable ambidextrous shape
• Button customization support

Cons

• Wired connection only
• Less suitable for mobile work

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

The low-profile body is designed to reduce arm and wrist movement while taking up less desk space than a traditional mouse. A silver metallic finish gives it a refined appearance, and laser tracking supports precise cursor control. Its ambidextrous construction accommodates either hand.

KensingtonWorks software provides button customization, allowing shortcuts or other assigned functions to better match the user's routine. The wired connection keeps power and data handling simple, making this suitable for a desk where USB access is consistently available.

Unlike the full SlimBlade Pro, this version is tied to its wired connection and does not present the same broad connectivity or programmability story. Its appeal instead rests on the streamlined shape, solid rating, and ability to replace a mouse without taking up much room.

Low Profile for Crowded Desks

The shallow housing leaves more usable desk area than a standard mouse. It can sit close to a keyboard, allowing the forearm and wrist to adopt a more relaxed, supported position.

Accurate Tracking in a Streamlined Shell

Laser tracking supports controlled cursor movement, while KensingtonWorks adds a layer of personalization. The result is a restrained but capable wired trackball for everyday work.

6. Orbit Wireless with Scroll Ring – Flexible Everyday Wireless Control

Orbit Wireless with Scroll Ring

40mm spherical tracking ball

Bluetooth and 2.4GHz wireless

Four selectable DPI levels

Detachable cushioned wrist rest

The Orbit Wireless Trackball with Scroll Ring combines familiar Orbit ergonomics with both 2.4GHz and Bluetooth connectivity. Its 4.2 rating reflects a versatile wireless option for users who want a physical scroll ring, adjustable cursor speed, and a detachable wrist rest.

Pros

• Two wireless connection options
• Physical scroll ring
• Four cursor-speed settings
• Encrypted 2.4GHz connection
• Mac and PC compatibility

Cons

• Bluetooth version is dated
• Wrist rest adds bulk

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

The 40mm hard-surface ball is designed as a precise sphere and uses optical tracking for smooth cursor movement. Four DPI settings—400, 800, 1,200, and 1,600—let the user move between detailed editing and faster navigation. The scroll ring handles vertical movement through pages and documents.

Dual wireless connectivity supports different computer arrangements. The 2.4GHz option includes 128-bit AES encryption, while Bluetooth offers cable-free pairing. KensingtonKonnect enables function assignments and speed adjustments, and the ambidextrous design makes the device suitable for both hands.

The Bluetooth implementation is limited to version 3.0 and LE, and the wrist rest makes the overall package larger than the most compact Orbit designs. Even so, the combination of a scroll ring, four speed levels, secure wireless operation, and broad Mac and PC support makes this a well-rounded wireless choice.

Choose Your Wireless Connection

Bluetooth is convenient for direct pairing, while the 2.4GHz receiver can be useful in busy shared environments. AES encryption adds a security layer to the receiver-based connection.

Cursor Speed for Different Tasks

Four DPI levels provide a useful compromise between fine positioning and quick cross-screen movement. The chosen level can complement the physical scroll ring for mixed document and navigation workloads.

7. Orbit Wireless Touch Scroll Ring – Most Compact Wireless Option

4.2Editor scoreCheck price on Amazon

Orbit Wireless Touch Scroll Ring

Compact 32mm tracking ball

Bluetooth LE connectivity

USB nano receiver support

Touch-based scroll ring

The Orbit Wireless Trackball Mouse with Touch Scroll Ring prioritizes compactness and straightforward setup. With a 4.2 rating, a 32mm ball, plug-and-play operation, and support for smaller hands, it targets users who find larger trackball housings too imposing.

Pros

• Very compact footprint
• No required driver installation
• Two wireless connection options
• Designed for smaller hands
• Customization through KensingtonKonnect

Cons

• Smaller ball limits surface area
• Touch scroll differs from wheel

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

Its compact ball occupies little desk space and is operated with less arm and wrist movement than a conventional mouse. The touch-sensitive ring provides a different scrolling experience, allowing movement through pages and documents without the resistance of a physical rotating wheel.

Bluetooth LE and the USB nano receiver offer wireless flexibility. No drivers are required for basic operation, and KensingtonKonnect provides a customized productivity experience for users who want to assign functions or adjust the device to their routine.

The main limitation is the smaller ball, which offers less surface area for slow, precise adjustments than the 40mm and 55mm models. The touch ring may also take some adaptation. Even so, this is an effective pick for a cramped desk, a smaller hand, or a user who values minimal desk usage above extensive controls.

Minimal Desk Space Required

The small housing and 32mm ball make this one of the easiest Kensington trackballs to fit into a limited workspace. It also suits users who prefer a smaller pointer device.

Fast Setup and Flexible Pairing

Plug-and-play behavior removes much of the setup friction. Bluetooth LE and the nano receiver let the user choose between direct pairing and a dedicated receiver workflow.

8. Orbit Optical Trackball – Simple Plug-and-Play Pointing Device

4.0Editor scoreCheck price on Amazon

Orbit Optical Trackball

Medium 40mm tracking ball

USB 2.0 wired connection

Optical tracking technology

Compact ambidextrous housing

The Orbit Optical Trackball is a direct, uncomplicated option for users who want a compact pointer device and little else. Its 4.0 rating reflects a straightforward wired design built around optical tracking, a medium ball, and plug-and-play USB installation.

Pros

• Simple plug-and-play setup
• Precise spherical ball
• Compact desk footprint
• Works with either hand
• No battery management

Cons

• No stated button customization
• Limited advanced feature set

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

The 40mm ball is engineered as a perfect sphere to support smooth and accurate movement. Its compact footprint takes up less space than the space normally required to operate a conventional mouse, while the ambidextrous body works for both right- and left-handed users.

The wired USB 2.0 connection avoids wireless pairing and battery replacement. That makes the device suitable for a permanent workstation, a shared office computer, or any setup where reliable plug-and-play operation is the priority.

The supplied specifications do not highlight programmable controls or a physical scroll ring, so it is less versatile than the more feature-oriented Orbit models. Its value lies in a straightforward optical trackball that performs the basic task cleanly and occupies little desk space.

No-Fuss Computer Connectivity

The wired installation removes the need to pair devices, update receivers, or monitor batteries. It can be a practical choice for office computers used by multiple people.

Comfortable Two-Handed Design

The symmetric shape removes a strong handed bias. Its smaller footprint and medium ball also make it less visually and physically imposing than full-size premium trackballs.

9. TB675 Wireless Vertical Trackball – Best for Multi-Device Control

3.8Editor scoreCheck price on Amazon

TB675 Wireless Vertical Trackball

60-degree vertical housing

34mm thumb-operated ball

Bluetooth, 2.4GHz, wired

Four-device selector

The Kensington TB675 Wireless Vertical Trackball is the most unconventional entry in the guide, combining a 60-degree vertical tilt, a 34mm thumb-operated ball, four-device support, and nine programmable buttons. Its 3.8 rating is the lowest listed, but it offers a genuinely specialized ergonomic and multi-device feature set.

Pros

• Natural 60-degree wrist angle
• Switches among four devices
• Nine programmable buttons
• Metal four-direction scroll wheel
• Rechargeable wireless design

Cons

• Lower customer rating
• Thumb operation requires adaptation

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

The contoured 60-degree shape is designed to support more natural wrist and thumb positioning and is intended for average-sized hands. A high-precision optical sensor tracks the thumb-operated ball, while four DPI settings ranging from 400 to 1,600 support both detailed work and fast navigation.

Triple connectivity includes a 2.4GHz dongle with 128-bit AES encryption, dual Bluetooth, and wired USB-C. A built-in selector allows movement among four connected devices. The metal four-direction scroll wheel handles vertical and side-to-side navigation, and KensingtonKonnect can customize all nine buttons, including two assignable side buttons.

The specialized thumb layout requires a learning period and may not suit users who prefer a centered ball. Its lower rating suggests it has not found as broad an audience as the conventional Orbit and SlimBlade designs. Even so, it is the strongest choice here for a multi-device vertical workflow that values programmable controls.

A More Vertical Pointer Experience

The 60-degree angle changes how the hand approaches the device, reducing the need to reach forward and across the desk. The ball is controlled by the thumb, so users need to adjust their grip and desk habits.

Productivity Across Four Devices

The device selector and three connection modes make the TB675 useful for users moving between a laptop, desktop, and additional connected systems. Programmable buttons add shortcuts for application-specific workflows.

The Kensington Slimblade Trackball has the highest customer rating in this group at 4.5. Its low-profile form and established model designation, K72327US, position it as a proven alternative for users who want the space-saving and reduced-movement benefits associated with the SlimBlade family.

Pros

• Highest customer rating
• Low-profile desktop design
• Compact ergonomic footprint
• Established Kensington model
• Suitable for extended productivity

Cons

• Limited supplied specification detail
• Older model family

Compared with a traditional mouse, the SlimBlade concept places the ball within a slim housing close to the desk. This can reduce the amount of arm and wrist movement required to move the pointer and free up desk space around the keyboard.

The supplied information identifies the model as part of Kensington's SlimBlade range, while the separately listed wired SlimBlade model provides further context about the family's low-profile shape, laser tracking, ambidextrous layout, and KensingtonWorks button customization.

Because the detailed feature listing for this entry is limited, it is best evaluated as a straightforward, proven trackball rather than a highly programmable wireless platform. Its strong rating and low-profile construction make it attractive for users seeking a familiar desktop alternative to a mouse.

A Familiar Trackball-Style Workflow

The pointer moves by rotating the ball rather than pushing a mouse across the surface. Once the motion becomes familiar, it can provide a comfortable way to navigate while keeping the device stationary.

Low-Profile Desktop Appeal

The slim form is designed to fit naturally near the keyboard and preserve desk space. It can be especially useful in compact offices where a full-size mouse and generous movement area are impractical.

Buying Guide – How to Choose the Best Kensington Trackball

The most suitable Kensington trackball depends on your desk, hand position, computer setup, and need for specialized controls. Comparing these factors before buying can prevent an expensive mismatch.

Ball Size and Tracking Style

Ball size affects precision, the amount of surface area available for slow adjustments, and how much finger movement is required. The 55mm balls in the Expert and SlimBlade Pro models support fine control and are attractive for detailed work, while the 40mm Orbit balls provide a familiar middle ground. The 32mm ball in the compact wireless Orbit is easier to manage for smaller hands and tighter desks, and the TB675 uses a thumb-operated 34mm ball within a vertical housing.

Choose a larger ball when precision and slow cursor positioning matter most. Choose a smaller ball when compactness, portability, or a lighter touch is the priority.

Wired Versus Wireless Connectivity

A wired trackball provides a stable connection, requires no batteries, and is ideal for a fixed desk. Wireless models reduce cable clutter and make it easier to move between computers. Kensington options include Bluetooth, 2.4GHz receivers, and, in some cases, a combination of all three. The SlimBlade Pro can also operate through its supplied USB-C cable.

Prioritize wired operation if your computer remains in one place. Choose wireless if you travel between desks, use hot-desking arrangements, or want a cleaner workspace.

Programmable Buttons and Software

KensingtonKonnect and KensingtonWorks support button assignments, cursor-speed changes, and other personalization, although specific options vary by model. The SlimBlade Pro stands apart with eight sets of programmable buttons, while the TB675 provides nine programmable buttons. The Expert supports a four-button design, and several Orbit models offer two customizable buttons. ChromeOS customization is limited on some Orbit products even when standard HID functions remain available.

Count the shortcuts you genuinely use before paying for a complex control layout. Programmable buttons are valuable for specialists but add little to a simple browsing or office setup.

Ergonomic Shape and Hand Size

Kensington trackballs range from low-profile and ambidextrous designs to the deliberately vertical TB675. The SlimBlade models emphasize a shallow desktop footprint, while conventional Orbit models use a centered ball and symmetrical housing. The vertical model places the ball under the thumb and angles the body 60 degrees. Fit is personal, so hand size and previous trackball experience deserve careful consideration.

Choose a symmetrical centered-ball model for the most familiar transition from a mouse. Consider the vertical model if you want a more dramatic posture change and are willing to adapt to thumb operation.

Scrolling Method and Document Navigation

A physical scroll ring is useful for long documents because it offers a clear mechanical action and can be spun quickly. The Expert, wired Orbit, and wireless Orbit with Scroll Ring include this feature. The compact Orbit wireless model uses touch scrolling, which reduces physical movement but may require a different technique. Other models may rely on standard click controls and software-adjustable scrolling speeds.

Choose a physical ring for intensive reading, research, or spreadsheet work. Consider touch scrolling if you prefer a flatter, more minimal control surface.

Wrist Rest and Long-Session Comfort

Comfort over long work periods depends on more than the marketing term ergonomic. Ball size, housing height, hand position, wrist support, and fit all influence the experience. The Expert, Orbit with Scroll Ring, and wireless Orbit include detachable wrist supports. The SlimBlade family uses a low-profile body, and the TB675 uses a pronounced vertical angle. A detachable rest can be valuable because it allows the user to reposition the device and adjust support as needed.

Look for a shape that keeps the hand relaxed without requiring an awkward reach. Removable support is useful when a wrist rest helps during typing but interferes with the user's preferred trackball posture.

Battery and Charging Routine

Battery design affects desk convenience and travel readiness. Wired Orbit models need no battery, while wireless models use receiver or Bluetooth power. The SlimBlade Pro has a rechargeable battery and is stated to last four months on a single charge. The TB675 is also rechargeable, while other wireless Orbit models use their own integrated power arrangements. Rechargeability reduces replacement waste but requires access to a cable.

Choose a wired or disposable-battery model for maintenance-free fixed use. Choose a rechargeable model if you prefer one charging routine and frequently work away from a power outlet.

Operating System and Workspace Compatibility

Most models support Windows, macOS, and Chrome OS to varying degrees, but details matter. The Expert supports macOS 10.14 and later and Chrome OS 44 and later, while the basic wired Orbit lists macOS 10.8 and later. Some ChromeOS configurations provide HID functionality without complete customization. Windows ARM-based systems are not currently supported by the Expert or SlimBlade Pro.

Check the current compatibility list before ordering, especially if you use an ARM-based computer, a specific macOS version, or ChromeOS. Confirm not only basic input but also the software features you plan to use.

How to Use and Care for Your Kensington Trackball

Begin by choosing a clear section of the desk and placing the trackball where your forearm can remain level rather than raised. Keep enough room to roll the ball freely, but avoid pushing it into a narrow keyboard recess. If the model includes a detachable wrist rest, position it so it supports the heel of the hand without forcing the fingers to reach upward.

Connect the device using its stated method: attach the USB receiver for 2.4GHz operation, pair through Bluetooth, or insert the wired cable. Install KensingtonKonnect or KensingtonWorks when you want to change button assignments, cursor speed, or scrolling behavior. Begin with moderate cursor speed and increase it gradually; a setting that feels slow during testing often becomes comfortable after the user learns the movement required.

For care, wipe the ball and exposed sensor areas with a soft, lint-free cloth, and avoid abrasive cleaners or excessive liquid. Keep the ball from falling off the housing, clean between the ball and the body if debris accumulates, and store the device in a dry location. For wireless models, follow the battery guidance in the manual and remove rechargeable batteries before long-term storage if the manufacturer recommends it.

Frequently Asked Questions

Is a Kensington trackball better than a regular mouse?

A trackball can be more comfortable for some users because the device stays stationary while the ball is rotated. This reduces repeated pushing movements and may suit people who prefer a fixed pointer position. Personal preference matters, however, and users accustomed to a mouse may need time to adjust to a smaller or larger ball.

What is the difference between the Orbit and SlimBlade trackballs?

The Orbit family generally uses smaller, more compact centered-ball designs, with several wired and wireless versions available. The SlimBlade family uses a low-profile housing intended to reduce desk space and arm movement. The premium SlimBlade Pro also adds rechargeable power, multiple connection methods, a 55mm ball, and extensive programmability.

Is the 55mm Expert Wireless ball better for precision?

The larger 55mm ball provides more surface area for slow and deliberate positioning, which many users find helpful for detailed editing or precise cursor placement. It is not automatically better for everyone because the larger housing occupies more space and may feel less comfortable for users with smaller hands. The Orbit's 32mm and 40mm options provide more compact alternatives.

Do Kensington trackballs work with Mac and Chrome OS?

Many models support Mac and Chrome OS, but the operating-system versions and level of software customization vary. Some ChromeOS devices can use standard trackball HID functions without allowing customization through Kensington software. Review the listed compatibility details for the exact model and operating system you intend to use.

Can I customize the buttons on a Kensington trackball?

Models that support KensingtonKonnect or KensingtonWorks can assign functions to some buttons and adjust cursor or scrolling speeds. The number of customizable controls varies from two buttons on several Orbit models to eight sets of programmable buttons on the SlimBlade Pro. The TB675 also provides nine programmable buttons, including two assignable side buttons.

Should I choose a wired or wireless Kensington trackball?

A wired trackball is generally simpler for a permanent desk because it needs no battery and avoids wireless pairing. Wireless models are more convenient for multiple computers, shared spaces, and travel because they reduce cable clutter. The SlimBlade Pro and TB675 offer the broadest connection choices, including Bluetooth, 2.4GHz, and wired operation.

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

A scroll ring rotates like a dial and provides tactile feedback as you move through documents. Touch scrolling detects a finger movement along the ring without requiring the ring to rotate. The physical ring may feel more immediately familiar to mouse users, while touch scrolling creates a flatter and more minimal control surface.

Is the vertical TB675 suitable for every hand?

The TB675 is described as well suited to average-sized hands and uses a thumb-operated 34mm ball. Its 60-degree vertical design deliberately changes hand and wrist positioning, so it may take longer to learn than a centered trackball. Users with small hands or those who dislike thumb movement should consider the traditional Orbit or SlimBlade designs instead.

Final Thoughts on Choosing the Best Kensington Trackball

The Kensington Expert Wireless Trackball is the strongest general recommendation because it combines a large 55mm ball, a physical scroll ring, removable wrist support, and both Bluetooth and 2.4GHz operation. The SlimBlade Pro is the most premium and programmable option, while the basic wired Orbit delivers the most approachable value.

Prioritize the features that match your actual workload. Choose a compact Orbit for limited space, a wired model for a permanent computer, a scroll-ring model for long documents, and the TB675 if a vertical posture and four-device switching are central to your setup. Programmable controls matter most for users who rely on application shortcuts rather than basic pointing.

Customer ratings and product availability can change, and current prices vary by retailer and configuration. Check the latest product details, operating-system compatibility, and current cost on the linked listing before making a final purchase.
