The track ball gets stuck or seams to get stuck once in a while.

I'm not too impressed with this trackball, I am used to the old style Logitech trackball & this is hard to get used to. They call it "ergonomic" that ain't what I've been calling it! Note to Logitech: start making your original trackball again, PLEASE!

Ok product, the ball seemed to wear OK very quickly. Really good for people with bigger hands

The key sticks. Brand new out the box. It sticks. Gonna have to take it back. Get nother one.

I did not like the trackball movement from the thumb. Maybe I am just old but it wasn’t for me

My wife laughs at me because I use a trackball but I love it. Easier than a regular mouse. I'm on my third one now. Hope they continue to make it. It should be cheaper though.

Nice little mouse but my thumb just could not get the ball to move right.

Not my favorite trackball mouse. It was a little different than what I'm used to using.

Logitech has outdone themselves again. This is the most ergonomic mouse to date. This thing is smooth as glass, and easy to get used to. The mouse fits perfectly in my hand and the secondary functions are all super easy to get to. The ball is extremely smooth and very accurate, and its not heavy or bulky. Anyone who has problems with their wrists or hands would do well to buy this mouse. I've been using it hardcore for the last few hours and have no fatigue nor soreness and I'm in my 50s. Just plug up the USB plug and check your batteries, and your computer will automatically find it and you can get right to using it. Space being an issue for me, I really love the roller ball motion of the pointer and I use dual screens. This thing zips between them with ease. You can't go wrong with this mouse

Unable to use it. Software not available to use with my Laptop

Precision failure . Not useful for excel or video editing .

Replaced a mouse with this trackball. Too soon to make a recommendation.

It works fine and I'm a die-hard logitech trackball user (since the Trackman Marble from the 90's), so I'm keeping it. I really like that this version connects by bluetooth so I dont need to use the dongle in a USB port. But I really dont like the feel when clicking the wheel (it barely pushes and wants to roll under your finger when you use it). The M570 click wheel had a better feel and response. And for some reason, when I roll the ball, I occasionally feel what I can only describe as a "groove" or a "bump" in the ball that I pass over. But there is nothing on the ball, so I guess its just in the way the socket holds the ball. But its only once in a while. Weird. Price has gone up too.

The only reason I gave this a low rating is because of the ball. It doesn't feel sturdy enough, and it made me roll all over the place on the screen, it's like the ball isn't heavy enough to maintain control. It wasn't my cup of tea so I returned it.

I wish the whole mouse moved. It was too hard to learn how to use the ball. My job is too fast paced to handle the learning curve. Will be returning.

I have used this type of mouse for as long as i can remember. So much more comfortable on the hand. Worth paying a little more foa better mouse.

The Logitech M575 trackball is a refresh of the M570, and takes its place as their new "standard" trackball. It makes minor design tweaks (all good), is supported by the modern "Logi Options" software for customization, and still retains the comfort and smooth performance of its predecessor. While it lacks some of the fancy features of Logitech's MX Master line, it's priced well for what you get. (In the interest of full disclosure, Logitech provided me with an Ergo M575 in exchange for writing this review but all opinions here are my own. I also own its immediate predecessor, an M570 that I purchased and used while working remotely during the COVID-19 pandemic.) After beginning to develop recurring thumb tendonitis in my mouse-using hand, I decided to experiment with a trackball instead of a standard computer mouse. Logitech is my go-to brand for mice, and so I purchased an M570 to use as an alternate to my MX Master 3 mouse. While there's a much smaller market selection for trackballs, the M570 was still priced reasonably and I expected Logitech quality. I was very pleased with the M570. It had a good quality feeling, and operated very smoothly. I liked that it was powered by a standard AA battery so that I would not have to worry about internal battery longevity. I found it very easy to adapt to trackball usage, and for some work I actually preferred it. It did not single-handedly cure my tendonitis issues, but I've been able to drastically decrease how frequently it flares up by switching back and forth between my mouse and trackball after a few days of use for each. (Of course, your mileage may vary and this is certainly not a medical opinion, just my anecdotal experience.) However, the M570 had one glaring downside - it was not supported by the Logi Options software that I already had installed, which could manage customization settings for all of the Logitech non-gaming peripherals I had used in the last couple of years. This meant giving up customization (for button actions and scrolling speeds), or installing extra software. Not a fatal flaw, but just an annoyance made all the more obvious by how well Logitech's ecosystem otherwise works together. I was quite happy to see that the Logitech Ergo M575 fixes this - it's now definitely supported by Logi Options! Beyond that, the M575 has some tweaks to the design of its shell, in the form of some subtle facets that break up the completely smooth curve of the M570. This better matches the design language Logitech uses for most of the rest of their modern mouse lineup. Coupled with a slightly different surface texture, it also means the M575 feels better in hand. Beyond that, the colors are tweaked a bit - again, they match the rest of the Logitech product line a bit more closely (though to be honest I slightly prefer the color of the old ball to the new). In operation, the new one is every bit as smooth and pleasant as the old, and the connection with Logitech's standard 2.4 GHz receiver is just as rock solid as ever. Plus, it still retains the simple AA battery for power! There really are few downsides. I do wish Logitech had added support for the M570 to Logi Options rather than requiring a new purchase. And, of course, neither the M570 or M575 are designed for left-handed use, but they don't pretend to be. (And I say that sympathetically as a southpaw for most fine-motor tasks - I've just adapted to right-handed computer use.) It doesn't sport the features of the MX Master line, such as on-the-fly switching between multiple computers, but Logitech makes the MX Master Ergo as a step-up if you're interested. (I'm personally not tempted until they have an MX Ergo with the new mag-wheel from the MX Master 3…) In summary, the M570 was already a good trackball, and I consider the Ergo M575 a home-run update. It updates both the design and software compatibility without ruining the things that made the M570 good. If you are trackball-curious this is a great model to try without breaking the bank.

it's ok....................................................just ok.

This is the finest “trackball” mouse that I have ever used. This is the 3rd or 4th replacement mouse that I’ve purchased and used.

I’m in love with this mouse. I will never use a traditional mouse again. I no longer have pain and numbing in my hand and wrist.
