Logitech Ergo M575S Wireless Trackball Mouse, Wireless Ergonomic Mouse with Bluetooth and Encrypted Dongle, Comfortable Thumb Control, Precise and Smooth Tracking, for PC/Mac – Graphite Blue Ball

Woks perfectly. Warranty cut from 3 to 1 year.
I’ve been using Logitech since the wired mouse/keyboard days, switching to wireless in 2012 along with moving from mice to trackballs to conserve desk space (and easy use at home on my recliner’s armrest). Like a microwave: once you go trackball (and develop some muscle memory in your thumb) you’ll never go back to a mouse you have to move your whole arm around to move a cursor. This review was done only a few days into using this new M575SReliability? I’ve only had one Logitech failure in 2018 – 2 months before the 3 year warranty expired. Logitech promptly replaced it without my incurring shipping charges. Was disappointed, and a little nervous, when I finally saw on the box for this M575S (in VERY small print) that the warranty has gone from 3 to one year since my last purchase in 2022. So… has the quality gone down too??? Only time will tell. Right now, after reading reviews for cheaper M570 trackball knockoffs of unreliability and flaky behavior I don’t mind paying more for a time-tested trackball.The M575S works as a trackball with expected basic functions out of the box (like every Logitech product I’ve purchased — 15 of them for my business and home. Just plug in the USB receiver and pull the battery connection paper tab to connect it. After downloading Logi Options+ app (and a PC restart. It won’t load without a restart) I could reassign buttons the way I am used to. The Logi Options+ app has been updated sometime last year I think, because it now works without the serious glitches it previously had disconnecting or not starting at all, or misbehaving inside the app. Works perfectly now. For another PC that I use for gaming I love the ability to make app specific trackball changes for a particular gaming app (or any app), like speeding up the trackball pointer just for that app to get across the screen without a thumb reset — then going back to a word processing app having it slow back down for cursor placement without having to reset cursor speed. For internet or word processing I like resetting the forward and backward keys to Copy and Paste. Just use the app to assign Ctrl+C and Crtl+V. I’ve found that very, very useful over the years.My only [small] complaint is that if you have a perfectly good Logitech K270 keyboard [ that has been around for years and working perfectly] that you cannot use with this M575S as the M575S uses the newer “BOLT” USB receiver. The work-around so you CAN use that older keyboard is to use both the old “Unifying” USB receiver that came with your K270 keyboard and the “BOLT” USB receiver at the same time. So, you use up 2 USB A ports — better than buying a new keyboard. It is GOOD, however that the same “Logi Options+” software will recognize both USB receivers and allow cursor speed,pointer & button programming so you don’t have to run 2 different apps. That’s not much of a problem with most PC’s coming with more than one USB A port even though most peripherals have moved to USB C.Like almost all mice and trackballs nowadays this one has a very high resolution ball for smooth scrolling and precise cursor placement.Battery life: I get about three months out of a fresh Duracell with heavy use out of my older M570’s and my M575 Pro. I’ve stopped using generic and rechargeable batteries. I DO always turn it off at night, weekends. You should too. And for devices that really last a long time like Logitech keyboards or less used mice or trackballs change the batteries at least once a year to forestall the formation of corrosion of battery terminals from batteries that are nearing end of life. Logitech devices have a pretty darn good coating on those battery connection terminal compared to many other battery-run devices, and I’ve only had one trackball (the 2012 one – Yes, still working!) start corroding. A visit to my workshop to fix it and it’s back in service.The weight is irrelevant to me since it sits in one place on a desk or leather armrest and is far less muscle/tendon strain than a moving mouse. The shape is very comfortable to the hand causing no pain at all after hours of continuous work, and the buttons are still working perfectly on all 15 of my M570 and M575S and Pro trackballs.If anything goes wrong with this M575S I’ll update this review. Right now I’m happy that I only spent 5 minutes installing and optionally programming the buttons and cursor speed for a game. If you don’t require that optional programming then your time will be less than 1 minute to use it.

Great mouse to purchase
The Logitech Ergo M575S Wireless Trackball Mouse (Bluetooth) is definitely an item worth buying. I only returned it because my job ended up purchasing one for me. Let me tell you how this product can make your life easier.First, it saves money because you don’t need to buy a mouse pad—the mouse doesn’t move at all. If you have arthritis or hand discomfort, this mouse can really help since there’s no wrist movement involved. You simply use the trackball on the right to move the cursor with your thumb. The buttons on the left make it easy to go forward and back while browsing.Overall, I’d give this a solid 5 out of 5.If you want this shorter, more technical, or written for a specific site like Amazon, just let me know.

Great mouse, functionality top notch
Love this mouse. I know people might be worried about adjusting from a traditional mouse to one of these, which is controlled using your thumb, but assuming you are right handed and don’t have arthritis in your thumb, this style of mouse is so much more natural and intuitive and easy to use that dragging your hand all over the place. The buttons have a soft buttery click, cursor movement is smooth, and it was very easy to set up on my computer. I use mine for work which is a lot of documents and excel and internet. I don’t have gaming experience but for what I use it for it’s great. I wish it were a little more affordable but I haven’t been able to find a similar style mouse for much cheaper so it might just be the price point. The only negative feedback I have is that this is supposed to be able to switch between multiple devices with just the push of a button when you have one device set up to Bluetooth and the other with usb transmitter- it’s called the easy switch. But it has never worked for me. I tried looking up videos and disconnecting and reconnecting but it just won’t work so unless I fully disconnect and reconnect to another device with Bluetooth- I’m really stuck using it on just one device. I really wish this feature was working, but alas.

Quiet, easy to install
It’s quiet as advertised, clicking thr right and left buttons is quiet. Connecting to lap top (HP) was quick. 2 options in connecting, 1 is Bluetooth and 2nd is the USB fob (I guess you can say the “usual” way). I chose Bluetooth, it was quick to connect. Came ready to use out of the box (came with battereies). I only used it for about 15 minutes and worked flawlessly. I highly recommend it.

J’utilise cette souris depuis 1 mois et je suis vraiment très satisfaite. L’adaptation s’est faite très rapide, soit en moins d’une semaine ! Excellent choix si vous avez des douleurs aux mains avec les souris classiques. La connexion se fait automatiquement.

Love this mouse! I’ve been using this mouse for quite a few months and have found that it doesn’t aggravate my Carpal Tunnel as much as a mouse you have to move around.It took a couple of days to get used to it but now I can’t ever imagine going back to a conventional mouse.I’m actually about to purchase a new one, as I dropped this one and the tracking ball popped out. At first, I thought, “Great! Now I can clean the inside of the tracking ball.”Unfortunately, the tracking ball itself must have found that one wormhole that occasionally opens up in my house and has been transported to a parallel universe, where parallel universe me is trying to figure out how she got 2 tracking balls, as I continued to rip apart my office to no avail.
