The Evoluent VerticalMouse 4 Right VM4R offers a unique shape that supports your hand in an upright neutral posture and avoids forearm twisting that most mice cause. Right-handed users will quickly become accustomed to the improved comfort; the grip is the same as an ordinary mouse, just turned sideways.
COMFORTABLE AND EASY TO USEThe shape is thoughtfully sculpted for uncompromised comfort and easy-to-reach programmable buttons. No finger contortions are needed to operate the buttons. The thumb rest has been reshaped to provide even more comfort over earlier versions.
NOW TWO THUMB BUTTONSA new bottom thumb button provides greatly extended functionality when used with the included driver.
EXTENDED LIP PREVENTS RUBBINGAn extra wide lip along the bottom edge prevents the last finger from rubbing the desk.
ADJUSTABLE LASER SENSORPointer speed controls on the side allow convenient adjustment without even releasing your grip from the mouse.
POINTER SPEED INDICATORS & LIGHTED EVOLUENT LOGOTop mounted LEDs show through the chrome thumb rest to indicate selected pointer speed including extra low (XL), low (LO), MD (medium), to high (HI). The logo illumination is pure eye candy and turns off when the system is in sleep mode to conserve notebook battery power.
