Kensington SlimBlade - trackball - USB - black

Comfort and productivity are at your fingertips with the SlimBlade Trackball. Your computing experience gets smoother, faster and easier with a ball that can do it all. In addition to the usual productivity gains that come with a trackball, with a simple twist of the ball, you'll be scrolling up and down pages. It offers better ergonomics, with less wrist and hand movement that will ease the pain of repetitive-stress injuries. KensingtonWorks sofeware also allows you to turn your trackball into the ultimate media controller so you can adjust volume, hit play/pause, stop, and forward/back. The sleek, low-profile design provides all-day comfort while advanced laser technology and a large 55mm ball deliver exceptional precision.
