Anker Vertical Ergonomic - vertical mouse - 2.4 GHz - 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.
