As its name suggests, this wired mouse is suitable for right-handers and smaller hands. The Evoluent4 Right Wired Small has great features like six programmable buttons, a direct-access DPI button that lets you set the pointer speed to one of four different values (800-1300-1800-2600), an illuminated Evoluent logo that turns off when the system is in power- saving mode, and... a lip that supports your pinky finger. Start your work with the Evoluent4 Right Wired Small and support your hand in an upright, neutral position that prevents twisting of the forearm. This vertical mouse promises the best comfort for your computer work.
