Kensington Expert Mouse Wireless Trackball Review: A large stationary pointer with a scroll ring

The Expert Mouse Wireless Trackball keeps the base in one place while your fingers move the pointer. It suits a desk where sweeping a mouse sideways is inconvenient. Its large center ball and ring have a different feel from a compact thumb-operated trackball.

Check space and shortcuts

Measure the footprint including the removable wrist rest. Four buttons and the scroll ring offer several ways to handle routine tasks. Check the configuration software against your operating system if custom shortcuts are central to your workflow. The symmetrical shape lets you try either hand.

Match the wireless connection

Kensington lists Bluetooth and a USB receiver. Pick based on which connections you can use on your machine. A receiver is useful on a computer where Bluetooth is unavailable but occupies a port. Choose this model when a stationary base and finger control fit the desk and the way you point.
