VM4R Evoluent Vertical Mouse 4 (Wired Right-Hand) Ergonomic Mouse

The VerticalMouse 4 (Wired Right-Hand) from Evoluent offers a new twist on the classic computer mouse: one that keeps your hand vertically in a #34;handshake #34; position while you #39;re pointing, clicking and scrolling. That means your arm sits neutrally without twisting, which is designed to afford extra ergonomic comfort during extended sessions.
