Customer Ratings & Reviews

Mouse works great. There's a button to engage a fine movement mode that makes the cursor move only slightly when the roller ball is moved. The feature is excellent, but the button is in a place where I keep hitting it by accident. Not a big deal

I love this thing. I’ve been using versions of this model of Logitech mouse for over two decades. It can be funky for folks to get used to, but it’s so easy and natural (and comfortable!) once you give it a few minutes.

Especially for those with tendinitis in the elbow, a trackball is one of the only ways you can continue to comfortably use a mouse these days. So the introduction of a new trackball by a major vendor is a great endorsement of this technology. And it turns out this is an EXCELLENT implementation of the trackball concept, taking the best elements of their recent MX Master mouse and applying them to the trackball. My mom loves it.

Not perfect, but I do like the adjustable ergonomic design. My wrist does not feel as strained compared with a traditional mouse. And because it's stationary, it's perfect for my compact desk space. Using the trackball does take some getting used to; had to adjust the speed on setup. And the scroll wheel does seem a bit loud...

Didn't really understand the value of this track ball mouse until I got it home and began using it with both my computers. I have limited room on my desk and now have one mouse device to control both computers with out moving around on the desk. Still learning the additional controls it offers.

I switched to a trackball mouse for several reasons, little desk space, but mostly ergonomics. I was using the previous version by Logitech, but this one is taking it to the next level and I'm so glad they did. It is so much better than the previous model in every way. If you have been thinking about switching to a trackball mouse, now is the time and this is the mouse. I currently use my mouse at work with Windows 7.

This is a game changer because it's way more comfortable to use than a regular mouse. Requires very little real estate because you're only moving your thumb. Great to prevent carpal tunnel and other wrist issues. If you work a desk job, do yourself a favor and invest in this trackball mouse - you will not regret. It does take a couple of days to get used it but it's no big deal. Battery life is GREAT

This trackball replaced my old MS Optimouse that they no longer make. I have always liked a trackball better than a mouse just for the fact that in a small space I don't have to move it all over the mouse pad to make it work. It is stationary and just my thumb has to be lifted to get the pointer repositioned anywhere on the screen. It is very convenient when you have limited space on your desk.

This this is perfect for any editor/graphic designer or VFX Artist! It has a great precision mode that helps when most trackball mice fail!

Perfect for gamers. I play wow and a wire is so inconvenient, this is perfect!

I have had several Logitech trackballs over the years. This is the most I have paid for one and I'm not sure it's worth the increase in price. I do like the tilt and find it makes the trackball even more comfortable to use. I prefer the back and forward button placement on the M570, but don't find them uncomfortable on this model. The connection has been consistently solid with no issues.

Huge fan of the original Microsoft PS2 trackball. Later purchased another Logitech but did not compare to my prior Microsoft this particular trackball has a comfortable angle and an adjustable magnetic base which makes it perfect for those of us who do not want to have torn rotator cuffs using our trackballs all day. Almost as good as the original Microsoft

Love it and I carry with it everywhere I go with my new laptop. It's ergonomic, best part is you can customize with it's software.

Very easy to use. Excellent quality. Worth the price!

Extremely comfortable easy to use although sort of pricey

Not much to say about this. I've been using trackballs since '95 or so. This one is better in that the angle feels better in my hand though. the price could be lower, but not much for what you're getting

Works great and battery last a while on one charge. I have multiple PCs at my desk: work, gaming and a raspberry pi. It is nice because I can easily switch between my gaming PC and work laptop. I do not use it to game but if I I need to quickly access my gaming PC it is just a click and I don't have to shuffle mice around.

My new favorite trackball mouse. Definitely helps alleviate the wrist pain I would get from using a traditional mouse. And I prefer the way this one feels and works over the Kensington Expert.

One of the best products I have ever used. Been a trackball fan for a couple of decades and this one is spot on. Allows for adjustable angles to be achieved by removing base plates that magnetically attach. Bought this to replace a corded one, and now the wife wants one at work too.

This is the second MX Ergo I have bought, I literally wore the other one out!! I love these mice, and I use them for everything from office work to gaming!!
