5.0 out of 5 stars How to survive carpal tunnel syndrome Dec 4 2009
If you live on a computer it happens but there are fixes

The first time I got it, I thought I was going crazy. My fingers started to cramp up and it hurt to click the mouse. Being left handed I switched right and within a month I couldn't touch the dang mouse without pain.

For a lifetime computer user, it was almost worse that the post polio syndrome.

Stopping, resting, operations - none of those things work. The problem is the rapid repetition with the hand turned 90 degrees. My fingers are tingling as I type since I wrote all day.

The solution is an ergonomic keyboard and the 3M mouse. The Microsoft Natural Ergonomic Keyboard 4000 is as good as any. There are some $200 to $600 keyboards that people swear by. I like this one and I'm too cheap to put out more than $100.

The real key to carpal tunnel is the 3M mouse. When your hand grips a regular mouse and you click, the nerve passing through the carpal tunnel is pinched because the wrist is twisted 90 degrees. Withe the 3M mouse, the wrist is straight with the arm and elbow.

The palm rests on the base the the rest is pure pleasure. In more than four years of use, my carpal tunnel has never come back. I keep a Microsoft mouse on the left but it still hurts to use it. The 3M mouse comes in two sizes, medium and large. Don't buy the wireless one - it is hateful. The cord also keeps the mouse on the desk. I broke a cordless one when it fell to the floor.

I bought mine for $79 from a specialty shop I found with Google. Amazon.ca is selling them now. I wish Staples did as well but they don't. At least Amazon.ca has free freight.

There is a good overview of carpal tunnel on ComputerWorld that takes the standard route to a cure. The carpal tunnel survival guide [...]

1.0 out of 5 stars Worst than the normal Mouse Feb. 20 2014

I would not recommend anyone buying this if you have any wrist issues. I would have returned it, unfortunately I lost the packaging it came in. I am back to using a regular mouse because this one was worst

5.0 out of 5 stars Takes a while to adapt, after that: brilliant Aug. 26 2013

As the title says. If you're running Linux it's possible to configure the input device such that you can press and hold the "middle" button (i.e. squeeze the handgrip) to scroll and release to end scrolling. Sadly on Windows you can't, but you still get the basic toggled scrolling mode.

3.0 out of 5 stars A huge adjustment March 25 2011
Verified Purchase
- Plug and play? Yes indeed. No problems here running with Windows 7 64-bit.
- Ergonomic? Yes. Rotating my forearm to the neutral position made a big difference in my mouse discomfort.

- No mouse wheel. Come on, this isn't a new invention! I mean really? Really!? 3M should at least mention this in the product description. The big mouse button on the side of the hand grip (which is best manipulated with your ring finger) is just a large middle mouse button. Many applications are not written to make use of the middle mouse button for scrolling so you are left using the keyboard arrow keys and grabbing onto the scroll bars like a Neanderthal.
- Mouse travels with your whole forearm rather than with your wrist. I suppose it isn't fair for me to make this a negative since this shift in locomotion is part of the ergonomic design, but it is a big adjustment to make. At work I use two screens with a combined width of 3200 pixels. That is a lot of real estate to cover with your forearm while still being able to achieve fine mouse control on certain tasks. I have tried adjusting my mouse speed, but can't find a happy medium. Perhaps they could address this with built-in mouse speed buttons... right after they add the mouse wheel!

Conclusion: If you have some serious carpal tunnel pain issues - this is a good choice since many of the sideways jacked up mice are really only half measures. Otherwise you will be frustrated and end up like me with a traditional mouse still hooked up for certain tasks.

5.0 out of 5 stars Perfect for those with wrist pain June 10 2004
By Carlton - Published on Amazon.com
This 3M Ergonomic Renaissance Mouse is great for those with wrist injuries or discomfort because it keeps your thumb pointed in the upward direction, eliminating pressure within the carpel tunnel area. I was pleased to find this new version that uses an optical sensor, a USB connector, and a new graphite color.
Mouse model number EM500GPS is supposed to be for those with palms 3.5 inches wide and less and EM500GPL is for those with palms 3.5 inches and larger. My palm is exactly 3.5 inches wide, I tried both, and the large size was much more comfortable. My fingers were much too cramped with the smaller mouse. I think the recommended cut-off between the two sizes should be about 3.0 inches.
Unfortunately, there are a couple of drawbacks. First, it's for right-handers only. Secondly, it is not quite as precise as a regular mouse because you can't use your fingers to fine tune the position of the pointer, so I occasionally miss target areas and have to reposition the mouse and click again. However, I still highly recommend this product because it helped eliminate my wrist pain, and that is the first priority! You can find info and drivers at the official 3M website: 3m.com/ergonomics/ergonomicmouse.jhtml

3.0 out of 5 stars Comfortable, but not that user friendly March 8 2007
By Peter Gallagher - Published on Amazon.com
I purchased this 3M Ergonomic mouse and the Evoluent Vertical Mouse2 at the same time to compare.

I really enjoyed the feel of the 3M mouse, but it is limited in what it can do. I need to scroll often with my kind of work. The 3M mouse does not have a scroll wheel it has a scroll button. When you push the scroll button, you then have to physically move the mouse up and down to scroll.

The Evoluent Vertical Mouse2 is pretty comfortable. It seems a bit light at times, so it takes a while to get used to it. I really enjoy the scroll wheel and the 5 programmable buttons; Left, Right, Middle, Wheel button (for your fingers) and a Back button (by the thumb) and the scroll wheel. Of course you can program each one to do what you want. You might want to visit Evoluent's web site to get the most up to date driver.

Although the 3M is slightly more comfortable then the Vertical Mouse2, with my type of work I need the functionality of the Evoluent Vertical Mouse2. If 3M had a scroll wheel I probably would have kept it, but I'm going to stick with the Evoluent Vertical Mouse2.

5.0 out of 5 stars Instant RSI relief June 14 2004
By Estelle Weyl - Published on Amazon.com
Verified Purchase
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.

4.0 out of 5 stars On my 3rd one, but still happy April 20 2006
By Charles S. - Published on Amazon.com
Verified Purchase
It's true, if you use this mouse for many hours a day then they have about 3 or 4 months of life - they start to double click like crazy, so you have to throw it out. I'm on my 3rd one, but it has allowed me to get my work done without pain. This seems like a small price to pay to reduce pain and allow me to keep working. I just purchased 3 of them so that I have about a 1 year supply. Maybe 3M will read these reviews and actually make a durable product, but why would they want to sell fewer mice?

5.0 out of 5 stars Really is absolutely amazing March 20 2005
By S. Allen - Published on Amazon.com
Verified Purchase
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.
