Customer Ratings & Reviews

Great flexibility with the trackball. It can easily adapt to my kind of usage for detailed work and navigation. Good investment.

I've been using Logitech trackballs for almost 30 years and love them. The MX Ergo has a great fit and the optional angle is great. However, Logitech failed miserably with their 'new' Logitech Options software. They removed the ability for the user to set the orientation that has been the most useful setting they had for their trackballs with the "Setpoint Settings" software. It provided the user the ability to set the vertical direction for whatever was comfortable for their thumb movement. But they removed the option and will not even respond to questions about restoring the functionality. Why they removed this long-time option and now expect you to adjust your thumb movement to their fixed orientation makes no sense at all.

Solid mouse but it’s good for taking off with other ergonomic mice if you have carpal tunnel

Slight learning curve but a great unit! Love that I can use it on two different systems.

Great shape and quality, however trackball can easily get clogged and not roll as easily until cleaned out. Also the MX keys is USB-C I wish this was as well… more cords.

Best mouse ever...Best mouse ever...Best mouse ever...Best mouse ever...

The product is good but didn’t help for my issue. great quality

My daily use mouse for a good reason. Work on my computer most all the day and this mouse feels wonderful and a good number of programmable features. Love it.

My hands tend to shake and make it difficult to use an ordinary mouse. This mouse works great for me. The programmable buttons are very useful.

Unable to learn purpose of magnetized lift on bottom piece. The mouse does not fit design

Amazing mouse! I love all logitech accessories. You can really feel the quality in this one.

Got this to replace my apple trackpad which was horrible - sadly bought the new one and still was not good. This has no issues, responds quick, and versatile.

Buttons have less travel than the m570; scroll wheel is much more tactile. Adjustable slope is great for comfort, especially the plus edition with the extra base plate. Back and forward buttons could use some work, shape wise.

Have loved trackballs for 30+ years, commercially and personally. Go Logitech!

This new mouse is so much better then my old one that i bought in 2011. Its more comfortable and easy"r to use.

Been a couple of years now and still working great!

Using this trackball mouse is so convenient when using your computer in different locations. You don’t have to worry about a surface to roll your mouse on.

Ever since I purchased this item and the keyboard, my copal tunnel and wrist has not bothered me a bit. This was the best purchase ever!!

This is a very nice mouse. Really love the ball and the smooth tracking.

Easy set up and a smooth trackball experience. Well built and comfortable on the hand.
