MT-50

The Trackball causes 20% less muscle tension in the hand, wrist and forearm than a conventional mouse. rnrnWith easy thumb control, you'll now benefit from superior tracking and precision during your daily routine. The precision mode (dpi) button allows you to seamlessly switch between precision and fast tracking modes.rnrnBecause you don't have to move your hand, this mouse is ideal for small workstations and crowded desks, and for people who can't move their arm/wrist. In addition, you can track smoothly on any surface.
