Kensington Expert Mouse Wireless Trackball
Kensington Expert Mouse Wireless Trackball Kensington is billing its new Expert Mouse Wireless Trackball ($100) as a solution to both cluttered desks and the strain of repetitive motion caused by using a traditional mouse for extended periods. Aimed at users performing tasks that require a high level of detail, Kensington claims the trackball boasts a superior level of cursor control and accuracy due to Kensington’s proprietary DiamondEye optical tracking technology. The company’s TrackballWorks software also allows users to adjust cursor speed for more precise control and customize functions for all four buttons, making it especially appealing to the left-handed.The scroll ring around the trackball allows for scanning up and down pages with ease and the included detachable wrist rest supports the hand and wrist for added ergonomic comfort. The trackball can connect via its included USB receiver, or over Bluetooth 4.0 LE to save a valuable USB port (although the TrackballWorks software will only work with a Mac when paired with the USB receiver). An auto-sleep function helps extend the life of the AA batteries that power the trackball. The Expert Mouse Wireless Trackball is compatible with MacOS 10.8 and later.
