The original Perfit Mouse, introduced in 1995, has provided over 100,000 users with unparalleled comfort and performance. Years later, the Perfit Mouse continues to be highly recommended by safety specialists, health professionals and ergonomists. In many instances, the Perfit Mouse is the only solution for eliminating or reducing hand and wrist discomfort while maintaining a high level of productivity. Proactive companies use the Perfit Mouse on mouse intensive workstations because it is highly effective in preventing mouse related injuries.
What's the secret? 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.
The new optical version adds the latest technology to the unique design of the original Perfit Mouse. A high precision optical sensor provides excellent cursor control. The key advantage of placing a scroll wheel above the thumb support is to reduce the strain on the index finger, which is already heavily used for the primary mouse click. Below the scroll wheel, the innovative two-position side rocker switch gives quick and effortless access to two additional programmable buttons
The table below is an aid to help you determine what Perfit Mouse Optical size you will need. You should measure your hand size using a ruler and compare the result to determine the recommended size.
- Measure on the palm side of the hand, from the tip of the middle finger to the first wrist crease with your hand held flat.
- Compare your measurement with the table below.
Note: If your hand measurement is between two sizes and you have a relatively thin hand, select the larger size. If you have a thick palm you should choose the smaller of the two.
