Customer Ratings & Reviews

Although this is the first trackball mouse I have used in quite some time, I have used many different kinds of mice over the years. I also own a Logitech MX Master 2S mouse that I absolutely love. This mouse has a lot of unique features to it that helps it stand out. The ability to adjust the angle of this mouse really allows you to tailor it to your level of comfort. The trackball works very well, and the sensitivity/speed button allows quick fine tuning and control. The back/forward buttons are placed well and my small hands didn't have much issue reaching them. What really separates this mouse is in Logitech's Flow software (free download). This allows you to quickly and seamlessly switch between multiple devices by simply dragging to an edge that you specify. This makes working between computers with one mouse almost effortless. You can also copy/paste and drag/drop files between devices. Overall, the trackball does take some getting used to but it finds it home on small desks and works well to minimize wrist strain.

The only reason I gave it 4 stars is because I can't really get accustomed to using it. It feels a little too bulky for me. The ball is smooth, everything is pretty accurate it's just that the design for me is too big. If you're looking for a trackball mouse, this is the one you're looking for.

I'm usually on my computer at least 4 hours a day. I have carpal tunnel syndrome and this mouse helps to relieve the strain on my muscles. No more batteries either! This mouse can last 4 months on a full charge. I gave it 4 stars because it is very large. Highly recommend.

Works great! Quick shipping, easy setup, efficient and smooth.

This is a very nice mouse. I'm used to moving my hands around, but that's the only thing that will take subs time hearing used to for me. Other than that, it's great. With extended use, this can help to relieve passion from long usage at your desk.

I bought this item years ago, it finely quit on me. I loved it because I have familia tremor. With this mouse I can control it. It’s the only one out there that gives me this option.

I almost exclusively trackball mice. Most of the time I'm on my laptop I'm sitting in a arm chair or recliner. This mouse is hands down the best one I've used. I use my laptop for both gaming and design and this mouse works well with both. The ability to switch between 2 different sensitivity settings with a click of a button is super convenient. Overall, if you are looking for a trackball mouse, you should get this one.

I love this mouse - I like the grip as well as the trackball.

I really liked it, very soft for my hand and very comfortable to work with.

I've come to expect a great deal of quality from Logitech and Innovation and I get that and more in this mouse. Who knew mice had apps, special customize buttons and wrist placement whether it's for gaming or professionalism this is truly the mouse of all millennium's I love it.

I've loved my track balls through out the years so the opportunity to get one with ergonomic customization and Flow control of two computers seemed perfect for upgrading my office pointing device. After one day, I'm back to the old as I just couldn't find a setting that was actually comfortable. The placement of the track ball itself is the problem, its to tight to the control, and the left and right click placement force you to keep your thumb unnaturally under your palm in order to fully operate. I do have large hands so I expect that this isn't a problem for everyone, but buyer be warned. On a positive note: I found the sensitivity to be great, and the customization options available through Logitech Options are super helpful.

Very useful item for graphic editing! Customizeable for speed-

I really like the size of the mouse in my hands and I have average woman hands. The one thing I didn't like is the angles I felt like none of them were quite right for my wrist when was too big one was too small there wasn't a perfect angle. I also like that it charges with the USB versus using AA batteries

Had for 4 months. Left button stopped depressing/clicking down. Under warranty. Contacted Logitech. After multiple emails, proof of purchase, etc...not good enough. Now, they want me to film a video to send to them. Really? No. Enough. Never, ever buying Logitech again.

I replaced the older logitech trackball bluetooth mouse with the mx ergo and am glad I did. The mx ergo has consistently connected to multiple laptops, hasn't stuttered (as with the older model) and doesn't feel cheap vs. the older model.

I have worked with computers for over 30 years. The first time I got a Logitech trackball (TrackMan Marble) was in the spring of 1999. since I had broken my wrist and bones in my hand, I needed a mouse that was easy to use. The Logitech trackball was the best solution. So I have over 20 years experience with Logitech trackballs. I have witness many iterations of this brand's trackball. I loved them all. EXCEPT I have one serious issue with them. The left mouse button WILL FAIL you after 2-3 years of heavy usage. I find it disappointing, and frankly, disgraceful that they cannot address this issue. It's been an known issue for a very long time. Do a search and you will find many have complained about this problem. There are tons of video on how you could fix this button failure. However, Logitech has made it more difficult to fix it by changing the screws on the bottom to the device. They would rather you buy a new one then to fix the problem. Since my trackball is now failing, this time after only two years of use, I have decided my 20+ years of loyalty is coming to an end. I have seen some cheaper models last longer. So in my opinion. this Logitech trackball is not worth the cost of having to replace it every 2 to 3 years.

Works great between my Mac and muy Samsung notebook. Great software which is easy to update. Tracking with the trackball is great

Great and responsive mouse first gaming mouse and i love it

Excellent mouse. Out of many designs of mouse out there, this is one of the best ergonomic designs you could get. Perfect

This is the best trackball mouse I have had to date!
