The Kensington Expert Mouse Wireless Trackball is a well-built and sturdy feeling trackball mouse with very good ergonomics. It feels solid and won't move around the desk, and has four large buttons that can be reprogrammed to suit your needs. Its design may not be for everyone as it can't be used with typical grip styles, but those looking for an ergonomic trackball mouse for office or multimedia use will likely find it comfortable and well-designed.

Our Verdict

6.2 Mixed Usage

A decent mouse for mixed usage. The ergonomic, trackball design may not suit everyone, but it has great ergonomics and large, solid buttons that should be comfortable for extended use. It's worth noting that due to its design, it cannot be used with any standard grip types.

Pros
  • Very good ergonomics.
  • Well-built design.
  • Fully compatible with Windows and MacOS.
Cons
  • Trackball design may not be for everyone.
  • Latency and performance only suitable for basic use.
  • Not portable.
8.0 Office/Multimedia

A great mouse for office or multimedia use. It has great ergonomics that should remain comfortable even during extended uses. Its large, programmable buttons are clicky and feel fairly durable. It works for both Windows and macOS and can be used with a USB receiver or Bluetooth, meaning you can pair to your Bluetooth laptop and a work desktop as well.

5.7 Travel

Not a good mouse for travel. Its large, trackball design is meant to sit on a desk and not move. The trackball rests in place via gravity and will fall out when turned upside down and the mouse itself is large and quite heavy.

3.3 Video Games (FPS)

This mouse is inadequate for FPS gaming. While it may be comfortable to most for long sessions, it has sub-par latency. Its trackball design may also not be ideal for gaming.

5.8 Video Games (MMO)

This mouse likely won't be suited for MMO games. While it has four programmable buttons, its unique design and poor latency make it a poor choice for games.

1.3 Ultra-Light Gaming

Bad for ultra-light gaming. This mouse has poor latency and its trackball design isn't meant for gaming.

The Expert Mouse has a professional design with an eye-catching red trackball in the center. It's quite bulky, but due to its trackball design it doesn't move across your desk.

While the Expert Trackball is quite heavy, it's not designed to move and the weight helps it stay in place.

The Expert Trackball isn't portable, by design. Its large and heavy base will help it stay in place on a desk, but it's not meant to be carried with you.

Build Quality

The Expert Trackball feels decently built. While it's entirely made out of plastic, it feels sturdy and doesn't creak or squeak under the weight of your hand. The scroll ring has some slight wiggle to it, but doesn't feel poorly made. There are small rubber feet on the bottom of the mouse to fully prevent it from moving on the desk.

The ergonomics of the Kensington Expert Mouse Wireless Trackball are very good. The removable wrist pad is comfortable but firm and provides good support of the wrist. Due to the design of this mouse, no standard grip can be achieved and your hand will generally stay on the trackball. The top right and left buttons may also be difficult for some to reach, depending how your hand rests on the trackball.

This mouse has dedicated software that allows sensitivity adjustments, though it simply changes the DPI multiplier in Windows. The default 500 DPI should be suitable for most office use but if you want to modify the speed of your cursor, set the DPI multiplier to your preference.

Note: Due to the trackball design, the DPI measurement of this mouse might not feel the same as a traditional mouse since you're not physically moving the mouse across the desk.

This mouse has four large buttons and a big scroll ring surrounding the trackball. All four buttons are programmable but the bottom two are left/right click by default. You can also configure special commands for pressing both top or both bottom buttons at once. On the rear of the mouse you'll find an on/off switch and a Bluetooth/USB receiver toggle.

Compared to other mice

The Kensington Expert Mouse Wireless Trackball is unique and quite different from the typical mice we've reviewed so far. This uses a trackball sensor and has an ergonomic design. It takes some time to get used to, although it can be a good option for office users.
