Evoluent Vert Optical Mouse 4 RH

Avoids forearm twisting for comfort and good health
The patented shape supports your hand in an upright neutral posture that generally avoids forearm twisting. Many users, including medical doctors, ergonomists and physical therapists, said the Evoluent VerticalMouse provides superior comfort and even relieved their wrist pain.
Comfortable and easy to use
The shape is thoughtfully sculpted for uncompromised comfort and easy-to-reach programmable buttons. No finger contortions are needed to operate the buttons.
Adjustable laser sensor
Pointer speed controls on the side allow convenient adjustment without even releasing your grip from the mouse.
Improved thumb rest
The thumb rest has been reshaped to provide even more comfort over earlier versions.
Pointer speed indicators
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).
Now two thumb buttons
A new bottom thumb button provides greatly extended functionality when used with the included driver.
Lighted Evoluent logo
The logo is pure eye candy. The illumination turns off when the system is in sleep mode to conserve notebook battery power.
Extended lip prevents rubbing
An extra wide lip along the bottom edge prevents the last finger from rubbing the desk.
Powerful and intuitive driver
Evoluent Mouse Manager for Windows provides extensive but easy to use functionality for 6 buttons through a simple and intuitive interface.
