Evoluent VM4R Vertical Mouse 4 Right Handed Wired

The shape is thoughtfully sculpted for uncompromised comfort and easy-to-reach programmable buttons. No finger contortions are needed to operate the buttons. Pointer speed controls on the side allow convenient adjustment without even releasing your grip from the mouse. The thumb rest has been reshaped to provide even more comfort over earlier versions. Top mounted LEDs show through the chrome thumb rest to indicate selected pointer speed including extra low (XL), low (LO), MD (medium), to high (HI). A new bottom thumb button provides greatly extended functionality when used with the included driver. The logo is pure eye candy. The illumination turns off when the system is in sleep mode to conserve notebook battery power. An extra wide lip along the bottom edge prevents the last finger from rubbing the desk.
