The VerticalMouse C Right from Evoluent is an ergonomic, vertical-standing mouse that is designed to prevent and alleviate wrist pains caused by prolonged mouse usage. The shape is made to be easy to grip, and it has a larger bottom lip to better support your pinky finger. Having your hands in a neutral position with this neutral grip position eliminates forearm twisting which can cause wrist pains. In addition, the Vertical Mouse C has an adjustable laser sensor with light-up pointer speed indicators. Its reprogrammable buttons are configurable using the Mouse Manager software, allowing you to have secondary functions for different programs.
