Evoluent VerticalMouse 4 Left VM4L


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. 



Approved ergonomic mouse of University of California at Berkeley

The Evoluent VerticalMouse 2 (an earlier model identical in concept) was evaluated in 2007 by a team at the health services clinic in UC Berkeley, including medical doctors, physical therapists, ergonomists, and administrators. It was found to be comfortable, easily adapted to, and promote a neutral wrist and forearm posture. It was the only vertical type mouse approved for staff use within UC Berkeley and for sale in the campus store at that time.
