Evoluent VerticalMouse D - Right handed USB wireless - Medium + Duracell NEW Optimum AA Alkaline Batteries [Pack of 4] 1.5 V LR6 MX1500

[ World’s First Mouse with 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. An extra wide lip along the bottom edge prevents the last finger from rubbing the desk.

[ Avoids Forearm Twisting For Comfort ] The ergonomic shape supports your hand in a handshake position. Since 2002, users continue to report that Evoluent VerticalMouse provides superior comfort and even relieves their wrist pain.

[ Easy-To-Reach Thumb Buttons ] Smartly-placed thumb buttons are both within easy reach at the top and bottom of a contoured thumb rest.

[ Adjustable Pointer Speed With Indicators ] Up to four lights show pointer speeds from slow to fast. A button behind the wheel enables the user to quickly change the pointer speed to suit different tasks: select higher speed (higher DPI) to make the pointer move faster for general use; select lower speed (lower DPI) to make the pointer move slower and more precisely for drawing, photo editing, etc.
