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
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.

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.

Popular Mouse Comparisons
The Kensington Expert Mouse Wireless Trackball is unique and quite different from the typical mice we've tested. 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. See our recommendations for the best mouse, the best ergonomic mouse, and the best wireless mouse.
The Logitech MX ERGO is much better than the Kensington Expert Mouse Wireless Trackball. The Logitech is better-built, and it has a more comfortable design. It also has much lower click latency, more programmable buttons, and you can adjust its CPI by increments of 100. However, the Kensington comes with a wrist rest, which is a nice touch.
The Kensington Expert Mouse Wireless Trackball and the Kensington Orbit Wireless Trackball with Scroll Ring are both wireless trackball mice designed for office use, and they perform similarly. The Orbit has significantly lower click latency, so it'll feel more responsive during use, and it has an adjustable CPI. Also, the Orbit has a lower profile some users may prefer. On the other hand, the Expert has more buttons, which can all be programmed, and has more cushioning built into its style.
the Logitech ERGO M575 is a better trackball mouse overall than the Kensington Expert Mouse Wireless Trackball. The Logitech has a more comfortable right-handed design well-suited to palm grip or claw grip. It also feels better-built and only uses one AA battery. On the other hand, the Kensington has an ambidextrous shape with a detachable wrist rest, but it has an unusual design that isn't compatible with standard grip types. It also uses AA batteries but needs two instead of one. Unfortunately, its latency is very high, though this shouldn't be noticeable for everyday tasks.
The Kensington Expert Mouse Wireless Trackball and the Kensington SlimBlade Trackball are two stationary trackball mice designed for office use. The Expert is a wireless trackball mouse that comes with a wrist rest. It has a higher profile and has a scroll ring around the trackball. On the other hand, the SlimBlade is wired-only, with a low-profile design that doesn't come with a wrist rest or a scroll ring. It has significantly lower click latency than the Expert, but both mice have very low fixed polling rates and CPIs that can't be adjusted.
