The Evoluent VerticalMouse 4 has a patented shape that supports your hand in a relaxed handshake position, yet requires no adaptation period. The vertical design eliminates the muscle tension created in the forearm, neck, and shoulder by other mice. Once you experience the superior comfort of this ergonomic pointing device, you will never go back to an ordinary mouse.

Eliminates Arm Twisting
The patented shape supports your hand in a relaxed handshake position that eliminates forearm twisting. You will quickly become accustomed to the improved comfort.

An ordinary flat mouse requires your forearm to twist away from its natural position.

Comfortable & 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. Right-handed users can choose from the regular size or a smaller size.

Improved Thumb Rest
The thumb rest has been reshaped to provide even more comfort over earlier versions.

Two Thumb Buttons
A new bottom thumb button provides greatly extended functionality when used with the included driver.

Extended Lip Prevents Rubbing
An extra wide lip along the bottom edge prevents the last finger from rubbing the desk.

Adjustable Laser Sensor
Pointer speed controls on the side allow convenient adjustment without even releasing your grip on the mouse.

Pointer Speed Indicators
Top mounted LEDs show through the chrome thumb rest to indicate selected pointer speed including extra low (XL), low (LO), medium (MD), to high (HI).

Powerful & Intuitive Driver
Evoluent Mouse Manager for Windows provides extensive but easy to use functionality for 6 buttons through a simple and intuitive interface.

The right-handed version of the mouse is available in two sizes for maximum comfort. Use the chart below to determine your size.

Regular: Hands 7″ and larger

Small: Hands smaller than 7″
