Customer Ratings & Reviews

Bought the MX Ergo Trackball for help with early arthritis. Love the size of this mouse. Great feel. I wish this was made without the trackball.

The trackball worked ok, I didn't like the fact the trackball itself was a little to sensitive to the touch which made it hard to zero in on something small. The tilt feature was nice to use to make it more comfortable.

if you leave it idle, it goes to sleep and usually it wakes up quickly, but not always. the more irritating issue is that it occasionally just does not respond and i have to let it sit for 30 seconds or so, until it finally decides to work again. its not defective, this is just crappy behavior. i will never buy a wireless mouse or keyboard again. i'm a professional software developer and this is unacceptable.

I have too many screens for this mouse. I need the faster speeds to move around but when you switch to the slower speed options the roller is difficult to control.

Had this item for about a year. Not a bad mouse. The buttons on mine stick now so i will have to replace it soon

I just want to say it works really well and wouldnt change a thing.

Developed double click exactly past the one year mark.

Thumb trackball usage hurts my wrist. I'm use to trackball on top, to be controlled by index and middle fingers. Probably can get use to it if only trackball you use.

While I love this product when it works, it is only 7 months old and has turned into a paper weight. Went through every trouble shooting technique I could find on line in addition to what logitech tech support had me do and had to RMA it. I guess I am lucky this happened before the year from purchase. I am to wait two business days and maybe they will process it. Freaking joke 10 year old wired $10 mouse still works no problem

It's the first and the last trackball in my life. I decided to give it a try and check how it goes but it was mistake. I've missed the time to return it so probably the only way I'll use it - connect to my smart-tv and use as a remote. The rubber stand constantly slides out from under it I always accidentally click this "slow down" (or whatever it names) button and can't understand what's going on for while after that. It deferentially doesn't worth $100+

Couldn’t get used to the tracker speed with the little ball on the mouse. Great product for anyone dealing with pain in wrist or shoulder.

Took this one back aand exchanged after using for a few days. Could not get used to trackball as compared to a regular mouse.

The best company making the best ergonomic mouses out there. Def buy!

Poor quality for high price. Had this for 30 days exactly (outside of return warranty of course) and the scroll roller started to squawk horribly (sounds like a legit mouse squeaking) and by the end of that work day the right and left click buttons stopped working. This has been on my desk, never dropped or even transported. Beyond upset i paid $100 for a paperweight.

Was awesome until the tracking ball stopped working. Did some research and that is apparently a huge flaw for this mouse.

Nobody purchases a fancy mouse with the expectation of building muscles in that finger. I was no exception. At first the mouse felt somewhat comfortable because it was different, but then when I got home and started using it a different story unfolded. Aside from having to ise my thumb a lot, I also found it difficult to nabigate around my documents and my inbox because I didn’t have any precisio, resulting in me using my thumb even more.

If the scroll wheel was like the MX Master it would be perfect.

Works great and very precise!! My team loves it for AutoCad!!

Build quality seems good, however it's missing key buttons that it's non-trackball counterparts offer. Also, the ball movements seemed a little jerky. You can tell this model is a few years old. It's 2023 and this needs a refresh badly.

$100 mouse and it's stopped working less than a year in with only moderate use in a consistent office space. love the mouse when it works, but not sure i can justify spending another $100 on a mouse.
