I like this but...


I would be more than happy to recommend this mouse if they were to remove the big giant huge button all together that always gets in the way that you really don't need for anything anyway. Until then this mouse is a no go. Look for something else.

I like the perdendicular handle so that I don't hit the bottom of my wrist on the desk and irritate the carpel tunnel. This is a real big giant plus. I wish that more mouses were like this

There is a big giant huge button going down the handle on the side of the mouse for scrolling. This button makes it very hard to grip this mouse. I frequently accidently push this button and then it messes up the screen. I can not grip the mouse right...

Ergo Mouse


After having carpal tunnel surgery I started using this mouse and I would not go back to the old style. I work on the computer all day and my wrist does not hurt like it did with the other mouse. I highly reccomend this mouse if you are showing signs...

It takes some getting used to as you are moving your amr and not just flexing your wrist. After a little use it becomes natural to use

I have a hard time using a conventional mouse, due to some physical limitations. This a great product for me to use. My arm, hand and shoulder no longer bother me using this mouse.

Great hand and arm position

Ergonomically friendly


Scroll clicker should be moved to he left more. It's hard to reach without totally letting go of joy stick so one can access it. It was hard to determine which size to choose. Believe correct size or smaller size might eliminate this problem.

Very nice !


The mouse does what it promises ! It's very recommendable. It just misses two things, one is the Wheel that we are used to. The other is way to adjust its sensibility, because it's quite different the way to use the mouse and at the beginning it's a...

Difficult to get accustomed to


I miss the "wheel" feature of my old mouse. The ergonomic mouse is difficult to use, and hard to pinpoint on small places (ie; check boxes). The scroll feature is overly sensitive

This is my second 3M ergonomic mouse. I bought the first one to address a serious carpal tunnel problem which it solved quickly. The first one was wired and lasted over ten years, including five years constant use at work. I'm leaving this one on...

This product feels great and has really reduce my RSI (Repetitive strain injury) symptoms after only three weeks of use. Overall I like the shape much more than other ergo mice but it is a different tactile feel and requires an adjustment period. Now...

Consumer review by: Matt (



First time using an ergonomic mouse. For myself, this mouse had a learning curve of about 2 weeks. Easy to use after that point, comes naturally. Had alot of wrist and finger RSI, and it cleared up in a month. I use this mouse for gaming, but it is a...


Product Specifications

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 requires forearm pronation and may cause pressure on the wrist and carpal tunnel area. 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.
