Customer Ratings & Reviews

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.

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

The mouse works really well. Had one several years ago that still works as new. Just make sure you clean the ball and the connectors inside the ball housing regularly.

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

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 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’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.

I much prefer Track balls over mice because they take up less desk space and the pointer does not move unless I move it. This one works very nicely.

I've popped my Trackball cherry, and it was worth it!! I'm being 100% honest when I say this is my first trackball mouse. Always wanted to try one and see if it really helps. To start with this one probably compares to smoking a cuban cigar as your first ever cigar, or driving a new Mercedes as your first car. Everything about this mouse is worth your hard-earned dinero. Many of you out there might be thinking , meh, what's the big deal, tried one trackball mouse, you've tried em all. Seriously, I'm a novice with them so be nice. It's super comfortable in your hand, and the trackball moves extremely smooth. Bonus, the ball is very easy to remove and wipe clean. Only thing I can think negatively on is the overall size, might be too large for kids, or a petite adult. It boasts a 24 month battery life. Obviously it's too early to tell , but they note on the box that's dependent upon individual use and computing conditions. I have owned many mice in my day as I'm sure you all have, and Logitech have always served me well. This is no exception to that rule. The Ergo M575 can connect via Bluetooth and USB, both of which connect quick and get you up and running without hiccups. So far I've used it on my PC, and my MacBook Pro. It works great with both, although much easier to customize with the PC, which can be said for many computer accessories. The program allows you to customize mouse speed, as well as the functions of all the different buttons (scroll wheel, and back/forward buttons). Here are all the different options as far as I can tell: Forward / Back / Next track / Advanced click / Calculator / Close window / Copy / Cut / Double click / Email / Gesture button / Input language / Keystroke assignment / Launch application / Left click / Lock / Maximize window / Media player / Middle button / Minimize window / Modifier keys / Mute / My Computer / My Documents / My Home / My Music / My Pictures / My Videos / New browser tab / Net track-fast forward / Open title / Open folder / Open web page / Paste / Play-Pause / Previous track / Rewind / Redo / Right click / Scroll left / Scroll right / Search / Show-hide desktop / Shut down / Sign out / Sleep / Switch operations / Switch screens / Task view / Trackball sensitivity / Undo / Volume up or down / Zoom in or out / Zoom reset / None I mean, look at that, it's insane. It can do everything besides make your coffee. I use the calculator a lot at work as I work so I've been utilizing that. You can change them for using programs like Photoshop or media intensive programs and find the combo right for you. Overall, I'm hard pressed to find any cons at all (again, y'all trackball aficionados might find some cons, and if you do, let me know how I'm coming up empty-handed) even the size I mentioned isn't that big a deal. My profession requires many hours on the computer every day. The amount of wrist life I'm probably gaining by using this mouse is worth it alone. Hat's off Logitech, well played.

Good mouse, have been using this type and brand for years and it is my favorite. One thing I did not like was that if you are over-harsh with it, the left and right click can break and it is not easy to fix, meaning you will have to buy a new one.

Really nice - took a little getting used to but I like it a lot. I don’t have to move mouse it stays put and rolls fast. Good product.

I love trackballs and this sadly the only good reliable trackball in town. the rest are all aftermarket or no names.

This mouse is one of the best trackballs that I have used, Smooth as butter. The track pads on the bottom are smooth. I give this 2 thumbs up!!!

I have used the earlier version of this mouse and this model is just as good, if you like this style of mouse.

Fast Connection! I love this new update to the mouse from Logitech! I love that it’s white! It goes awesome with my new decor.

Great quality mouse. Only issue is the ball is not smooth and gets tough sometimes. These do require a break in period so will wait for that to end and see if its smoothed out.

I have always loved the roller ball mouse. This one has great maneuverability and control. And I really like the color scheme.

The mouse works well, but too often is not "found" by the computer. Every troubleshoot offer has been utilized but the problem persists.

If you drop this mouse on hard floor the traek ball goes flying Sometimes the battery cover also pops off and the battery goes flying I have used this tyupe of mouse for 5 years Logiech should be amble to remedy this issue

IF YOU LIKE LOGITECH TRACKBALL MOUSE, THEN DON'T BUY THIS ONE. I GAVE THIS ONE TO MY GRANDSON TO USE ON HIS GAME SYSTEMS THE LARGER MOUSE WITH THE RED TRACKBALL IS GREAT BUT THIS ONE IS TOO SMALL FOR MOST ADULTS HANDS
