Approved ergonomic mouse of University of California at Berkley:

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
