5.0 out of 5 stars Instant RSI relief, June 14, 2004

By	Estelle Weyl (San Francisco) - See all my reviews (REAL NAME)

I felt the difference in my right wrist instantly. According to websites, "Ergonomic design keeps the arm positioned for natural, comfortable movement. It is clinically proven to reduce muscle strain and discomfort associated with Carpal Tunnel Syndrome and repetitive stress injury. The 3M Ergonomic Mouse is compatible using any USB port computer."

Ever notice that Gamers don't have carpel tunnel syndrome like most typists even though they likely spend more time at the computer? Well, 3M noticed! Your wrist sits on this ergonomic mouse like it does on a video game joystick. The weight of your hand is no longer carried by your wrist. Rather, your hand is relaxed on the mouse.

The relief in pressure on your wrist is instant. The cost may seem high, but it's less than a chiropractic appointment. Comes in 2 different sizes (small/medium and medium/large). This is a RIGHT handed mouse. You can program the left/right clicks if you are left handed, but the "joystick" is angled, so it's not as wonderful if you are a lefty.

Added note: The above review was written 2 years ago. It has been 3 years that I have been using this mouse. My wrist pain is completely gone. This mouse is so worth it. That being said, it is a P.O.S. as others have mentioned: the mouse does not travel well (it breaks if not protected in your computer bag) and breaks when dropped on hard surfaces -- I put a carpet under my desk and bought a glue gun to cut down on mouse costs. After gluing them back together, 3 have acquired the "double click" disease. Even with these drawback, I still feel that this mouse is worth it. I have purchased 8 over the past 3 years - I now keep one at work, one on my desk at home, and a "floater" for my home laptop that moves from room to room but does not leave the house unless carefully wrapped in it's original box. For "daily travel", because the 3M mouse has helped my wrist heal, I am now able to use a regular mouse, so I now keep a regular mouse in my backpack.

5.0 out of 5 stars Really is absolutely amazing, March 20, 2005

By	S. Allen - See all my reviews (REAL NAME)

Though it takes a little getting used to, once you adapt to this mouse it really is indispensible. After about two years of too much mousing at too many poorly adjusted tables, I had developed fairly regular pain in my right hand and wrist, so much so that I started favoring my left hand for carrying objects. After switching to this mouse and an ergonomic keyboard (the Belkin Ergoboard to be precise) this pain is completely gone and a bump that I had started to develop on a tendon on my right hand has almost completely receeded (and my doctor had said that it was caused by mousing). In other words, if you have any pain at all from mousing, you should get this mouse. It works well, is durable, and really does all that it should do. I can't recommend it enough.

1.0 out of 5 stars Beware of worsening problems, June 5, 2006

By	Adam Safran (Los Angeles, CA) - See all my reviews (REAL NAME)

I run the IT department in a small office (around 30 users). Four of the users who had turned to this mouse to deal with carpal tunnel issues initially found it quite comfortable. However, that changed over time with each one complaining of pain from the thumb to the wrist.

The problem, as far as I can tell, is that this mouse requires too much extension of the thumb -- far more than one would expect in a normal mouse. I'd suggest staying clear of it and replacing any that you may have purchased with an alternative that does not require as much thumb movement.
