Evoluent VerticalMouse 4 (Wired, Right-Hand)

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