Evoluent Vertical Mouse VM4 Small Wireless
Evoluent – world's first and original vertical handshake-grip mouse
The 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.
The bottom thumb button provides greatly extended functionality when used with the included driver.
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.*

An 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.
