3M Ergonomic Mouse, Optical, USB/PS2 Compatible, Small Size, Black (EM500GPS)

3M This mouse is clinically proven to alleviate pain and discomfort of repetitive stress injuries in the hand, wrist or arm associated with the use of traditional mice—which can pronate the forearm and wrist and typically presses the wrist and carpal tunnel area against the desk. The 3M Ergonomic Mouse has earned an Ease-of-Use Commendation from the Arthritis Foundation for its patented, vertical grip design that keeps your hand and wrist at a neutral angle, while the mouse works as a regular optical mouse. Grip the handle and rest your hand on the base. Use your thumb to left and right click. Optical sensor, USB/PS2 plug and play compatibility and a 6.5 ft. cord for flexible use. Available in original black design. For right-handed use. 2 year warranty.
