Black, Right handed, New in the box. The ONLY Mouse to Qualify and be Registered under Section 508 of the U.S. Rehabilitation Act! The AirO2bic Mouse has been designed to keep your hand and wrist in a "neutral" position, relaxing your muscles and eliminating the stress most mousing positions create in your hand, fingers, wrist and forearm. Relaxed muscles are not only more comfortable, but are less likely to tire, ache or injure. The AirO2bic Mouse can prevent repetitive stress injuries or if you're already experiencing problems, the AirO2bic Mouse can ease your pain. The AirO2bic Mouse is designed with the Wrist Guard; heel and sidewall, which stops the strain of wrists flexing in both the vertical and horizontal directions and allow for totally grip-less movement. This means your wrist doesn't have to drag the weight of your hand and you no longer need to grip your mouse with your fingers and thumb.
