Ease Of Use

Scrolling

Quality

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 little weird, but still nice to use.
I'm just starting to used and I'm feeling relieved and confortable.

Very nice !

Once you get used to it (about a week), you cannot go back to using any other mouse.  I can't stress how much this helps relieve wrist pain and even shoulder and neck pain.  The ergonomics are perfect.

Best Pain Relief - This Mouse!

3m.com

I've used this mouse for a week now and it has great potential. The problem I have is I have severe acrophy in my hands and it works for a while for me and then I have difficulty navigating it is not. The fault of the the mouse it is a great invention. I am working with the veterans administratiand some other alternatives but will probably keep this as a backup again. Anybody who uses a mouse a lot should really like this product.

The product is great for many people.

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

Difficult to get accustomed to

I've used these mice for about 20 years, since before 3M was making them.  They work well ergonomically, but I wish they were higher quality.  Buttons eventually break, and even when new things are wiggly and more noisy than necessary.  How about making a deluxe version that is really crisp, tight, and lasts well?  I'd pay two or three times as much for that.

I'd pay double if it were more robust

I am on perhaps my fifth Renaissance mouse, from when they used balls. Clearly I like it a lot. 
The good: it is the only mouse I know that puts your hand in the handshake position AND takes the weight of your hand and arm off the table, so that your arm muscles move the mouse instead of your wrist. That lets me spend 12 hours a day in front of the computer, if needed.
The less good: The weight of the hand rests mostly on the right side of the base, especially below the heel of the hand, where the base becomes narrow. The left side of the base takes almost no weight. And the base glides on five small, round, flat feet of slippery plastic (probably HDPE), almost paper thin, and one foot is right below the heel of the hand, almost right below the 3M logo. So that one foot takes much more weight than all the others. Believe it or not, that foot eventually wears out from friction and pressure, and disappears. Now the feet are uneven, and the mouse will then rock a little on its remaining feet, making the cursor leap around the screen. Also, a metal screw that secures the base protrudes out of the base slightly, and when there is no plastic foot providing clearance, the screw will scratch and drag on the table (I use a thin, hard mouse pad.) 
How to fix: I can think of several ways to fix these issues. One is to make the pads much wider and thicker. I notice many mice have a longish bar of material underneath to take wear. I would recommend only three large pads, so the mouse never rocks from uneven wear. Another way is to make the entire base from HDPE, so the load is spread and the wear is much slower. It would also help to replace that pan-head screw with a flat-head, so it doesn't protrude at all from the base. But the best approach, in my view, would be to redesign the mouse so that the base is centered on the heel of the hand, and not on the stalk. and move the stalk out to the left edge of the base. Thank you!

Terrific idea, could use a bit of refinement

I've been using this type of 3M mouse for maybe 13 years or so.  I am on mouse No. 5 and about to go to mouse no. 6.  Mouse after mouse, the left button starts failing after a couple years of use.  The left click either doesn't register, doesn't release, or registers and releases randomly when trying to hold the click down and drag.  It becomes impossible to use.  I am sick of replacing it, but this is the ONLY mouse that prevents me from having a great deal amount of pain from clicking all day/every day at work.  Unfortunately the durability and quality of this mouse is absolute garbage.  :(

Best Ergonomics, Absolute Worst Quality

3M Ergonomics

I have been a huge fan of this mouse for years.  I had a wired version for work and when it finally broke, I upgraded to the wireless version.  This mouse does not work with Windows 10!  When I try to use it on my brand new Dell laptop, the lag time is so poor, that it renders the mouse unusable.  I have tried adjusting the mouse pointer speeds, to no avail. I am distraught that I invested all of this money only to abandon my brand new mouse.

What happened to my favorite mouse?

I use this type of mouse severall years with much pleasure. This is my third mouse of this type. However, this year, only problems. My mouse fell from the table, and was broken. I purchased a new one. From that moment, I have constantly problems with the top button. It keeps 'hanging' after clicking. I 've got a new one from the store. Same problem!!!

What happened to my favorite mouse2

Nice mouse but the buttons failed in 2 mice after 2 years each.  Looked inside and the buttons were connected to the board with low quality wire that had corroded at all 14 solder joints! Having one go bad is a fluke but all 14 is a defect. Most likely they do not wash the flux off during manufacturing.  Hey 3M, how about forwarding this to someone who can make it stop happening?
