The Perific Ergonomic Mouse is designed on the principle that varying hand posture is the best way to prevent repetitive strain injuries. It can be used as both a conventional desktop mouse and trackball, as well as a wireless pointer. Its two sets of left and right buttons and unique design allow it to be operated in multiple positions. But good hand health comes at a price – the Perific Mouse retails for $119.
