Rated 1 out of 5 by from What happened to my favorite mouse2 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!!!

Rated 1 out of 5 by from What happened to my favorite mouse? 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.

Rated 5 out of 5 by from Perfect Mouse I switched to this mouse about 7 years ago, when I developed a pain in my wrist. I discovered the pain resulted from moving the mouse with my wrist my instead of moving it with my elbow and shoulder. Despite trying I could not change this habit with the conventional mouse - so I changed my mouse to the 3M Ergo mouse. It took a day or 2 to adjust, and because I had to learn to use this mouse from scratch I also learned to move it with a combination of elbow and shoulder movement. I have never looked back and the pain in my wrist disappeared. A wonderful device which I would recommend to anyone.

Rated 5 out of 5 by from Great design. Mouse 2.0 coming soon? I have been using this mouse for close to 20 years. First 2 were wired, latest is wireless. Reading some of the comments about it breaking is not at all what I have experienced. I have worn out the pads, but simply purchased new ones and it continues to work. I currently use a standard mouse with my left hand since it has the scroll wheel to zoom in the Pro/Engineer program. Any change of adding one soon? Could really make it a complete mouse with that functionality.

Rated 2 out of 5 by from good basic shape but mouse "button" needs redesign The basic shape and angle of the mouse is good. However, I get a sore thumb from the means of clicking, which is done by pushing your thumb sideways on a rocker switch at the top. Two (or even just one for the normal left click) mouse button(s) under the index and middle fingers built into the handle, like a trigger, would work better. As it is, I cannot use it.

Rated 1 out of 5 by from buttons broke after 2 years 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?

Rated 1 out of 5 by from Update driver is not available My computer has freeze problems when my mouse is connected, and has no problems at all when the mouse is disconnected. My support department advises to update my 3M mouse driver, but it is not available. So I cannot use my mouse anymore. It is very disappointing.

Rated 1 out of 5 by from The wireless version was disappointing! I bought this mouse a month ago brand new everything worked fine. Suddenly all my devices cannot recognize the dongle (it used to blink red when I would try to connect, now it just holds red and does nothing). The mouse is now landfill unfortunately. I would recommend getting the wired version as I have now read that I am not the only victim of the poor design of the dongle.
