3M This mouse is clinically proven to alleviate pain and discomfort of repetitive stress injuries in the hand, wrist or arm associated with the use of traditional mice—which can pronate the forearm and wrist and typically presses the wrist and carpal tunnel area against the desk. The 3M Ergonomic Mouse has earned an Ease-of-Use Commendation from the Arthritis Foundation for its patented, vertical grip design that keeps your hand and wrist at a neutral angle, while the mouse works as a regular optical mouse. Grip the handle and rest your hand on the base. Use your thumb to left and right click. Optical sensor, USB/PS2 plug and play compatibility and a 6.5 ft. cord for flexible use. Available in original black design. For right-handed use. 2 year warranty.

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!

On my 3rd one, but still happy  Apr 20, 2006 By Charles S.
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?

Cheap plastic construction  Sep 04, 2006 By John Fanning
I had pretty bad hand pain from my microsoft wireless mouse. I bought three of these based on the reviews I read here. The day I started using it the pain disapeared, however I gave my teenage son one too and that is when the bad news arrived. Within a week he had snapped the mouse in two. I figured he was just being a teenager until a month later when i broke mine in half. I took the third one and guess what, same exact way the third one broke. The base and the handle are connected with a plastic snap like joint. The joint occurs in the very place torque is likely to occur and there are three little tabs of plastic that are less than 1/8th of an inch thick keeping it together. Its amazing an engineer at 3M could think this was a good design. Oh well. I just threw them away, not sure if i could have returned them to 3M. They work so well ergonomically, once you get used to them, that I will probably buy more.

Superb mouse! Actually works. Solid design.  Aug 25, 2005 By TonyD "think41c@hotmail.com"
The 3m Ergo mouse is the best mouse for ergonomics on the market. The picture is misleading though. I thought that perhaps it was some sort of joystick type of mouse (which would still require moving the wrist, which wouldn't help really). It is one solid piece that does NOT move at all. The picture also hides the fact that it has 3 buttons, a left click (on top for the thumb), a right click (also on top), and one on the side (not shown) for the other fingers.

What you'll immediately notice about this is that when you start to use it, your wrist will not move at all and you will be using your arm to move the mouse.

I have no problems with the mouse treating a single click as a double click either. Perhaps the other people simply had a defective unit (or more likely, 3M was producing it poorly has revised their design to have it fixed).

In my own experiment with this mouse, I intentionally did NO other therapy for my wrist to see how much the mouse actually helped. My hand went from nearly totally unusable to not having hardly any pain (unless I use a regular mouse again, and/or type for extended experiods again) in less than 20 days. Clearly, healing has already started, and it's also happened in less than 1 month with this mouse.

For people that play first person shooters, I also use this mouse for games with no problem at all. And it took me about 1-2 days to get used to it. It's very "natural". Highly recommended.
