Evoluent Vertical Mouse 4 right hand/6 buttons/wired

The Evoluent VerticalMouse 4 has a uniquely patented contoured upright design which transforms the traditional palm down mousing position to a vertical "handshake" position which is more comfortable for many users. This mouse has a large lip along the bottom of the mouse to prevent the pinky finger from dragging on the desk, and contouring which provides comfort, reduced grip force and exceptional control. Performance-driven improvements include an instantly accessible pointer speed control button on the side of the mouse allowing the user to select between Extra Low, Low, Medium and High, giving users the ability to select the degree of precision they require for each task. An additional thumb button can also be assigned once a driver is installed.
