Anker 2.4G Wireless Vertical Ergonomic Optical Mouse, Black

The Anker 2.4G wireless vertical ergonomic optical mouse is designed to reduce forearm twisting and the resulting repetitive stress and pain. The vertical "handshake" position encourages a neutral wrist and arm alignment for greater comfort and better health. No finger contortions are needed to operate the easy-to-reach buttons. The thumb rest has been reshaped to provide even more comfort over earlier versions, and the addition of two navigational thumb buttons allow for smoother, faster web browsing.
