The Perfit Mouse Optical. Ergonomic, productive and comfortable? Certainly expensive at $109.95.
Through years of testing we have discovered a unique posture for the fingers, thumb and palm that is not only great for rapid target acquisition, but also allows maximum muscle and tendon variation throughout point and click operations. Variation is only one of the keys. We also found that when the hand is placed in this balanced posture, local hand muscles come into play. This minimizes the need for flexor muscles that are connected to the fingers through the carpal tunnel. Reduction of carpal tunnel activity is the key to preventing carpal tunnel syndrome.
I have had one of these for about a year now after getting RSI from a standard mouse. Pain is completely gone and the scroll and toggle buttons for the thumb are fantastic.
Cool, nice feedback. The toggle button does actually look quite neat. Still quite a price premium though! But what price health, eh? :-)
The company paid for it! ;-)
Didn’t realise it cost that much though :-0
