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 VM4SW VerticalMouse provides superior comfort and even relieved their wrist pain. (The statements herein apply to some current or past users of Evoluent VerticalMouse, but since everyone is different, Evoluent makes no claim or representation that the Evoluent VerticalMouse will prevent, cure, or mitigate any medical condition, disease, injury, pain or discomfort for all users)

Avoids forearm twisting for comfort and good health

Important Note: Touching the Evoluent Mouse when your hand is wet with alcohol-based hand sanitizer might eventually cause the paint to wrinkle. The product instructions sheet carries a warning about this fact. Please let your hand dry after each sanitizer application before touching the Vertical Mouse.

Approved 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.




The images below are of the regular right hand model

  • 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.

Comfortable and easy to use

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

Improved thumb rest

  • Now two thumb buttons - A new bottom thumb button provides greatly extended functionality when used with the included driver.

Two thumb buttons

  • Extended lip prevents rubbing - An extra wide lip along the bottom edge prevents the last finger from rubbing the desk.

Extended lip prevents rubbing

  • Adjustable optical sensor - Pointer speed controls on the side allow convenient adjustment without even releasing your grip from the mouse.

Adjustable optical sensor

  • 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).

Pointed Speed Indicators

  • Mini Receiver - The tiny 2.4 GHz receiver avoids being knocked off the side of a notebook computer.
