Evoluent VMDMW VerticalMouse D Medium Right Hand Ergonomic Mouse with Wireless Connection. The Original VerticalMouse Brand Since 2002

PREVENTS WRIST DISCOMFORT - Evoluent's ergonomic VMDMW gently supports your right hand in an upright neutral position. The patented shape prevents you from twisting your forearm like what you usually do with an ordinary mouse.
PROGRAM YOUR MOUSE TO YOUR NEEDS - Install the Evoluent Mouse Manager onto your computer to configure the VerticalMouse's buttons. Not only can you change their function but you can also set how the buttons work within different programs.
GROOVED BUTTONS - Your fingertips rest in a shallow groove on the buttons. This patented innovation secures the mouse in your hands and makes moving it much more precise.
