Ergoguys WIRELESS VERTICAL MOUSE DPI SWITCH 800 1200 1600 - Wireless - Radio Frequency - USB - 1600 dpi - Scroll Wheel - 5 Button(s) CST3645A

Ergonomic Vertical design allows a stress free natural hand position that allows the user to relax the hand muscles and wrist. The integrated hand rest lets the user rest their hand comfortably without touching the desk surface but can be removed to suit the user. The left and right switches are arranged to match the hand position so there is no "reaching" for buttons. The well placed precision scroll wheel also has a switch that can be customized.
