The Evoluent Vertical Mouse 4: Right Hand Wireless Bluetooth Mouse VM4RB features a patented, sculpted design unlike standard computer mice. The vertical design is intended to keep your arm in a neutral position, where the arm bones are parallel with one another. With reduced pronation of the wrist and less grip strength required, many users find that a vertical mouse provides immediate and long-term support, often completely eliminating wrist pain. The six programmable buttons are conveniently located so that the user does not have to change their grip and only minimal force is required to click. Available in a clean white finish, the Evoluent Vertical Mouse 4: Right Hand Wireless Bluetooth Mouse VM4RB is a mouse that is setting the bar both in ergonomics and in style.
