3M EM500 Ergonomic Mouse-Small-Graphite (black)
3M EM500 Ergonomic Mouse-Small-Graphite (black). The 3M Ergonomic 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 vertical grip design 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.
