Logitech M575 - Latin America

I owned the previous model of this wireless trackball mouse and have owned 3 Logitech mice so far, so I decided to upgrade to the latest version—and Logitech has done it again with another fantastic product! The improvements are noticeable, from the refined design to the seamless wireless connectivity and lack of any latency issue's. It offers incredible value for the price, combining top-notch quality with flawless performance. The precision and smooth tracking make it perfect for both work and everyday use, and the ergonomic design ensures hours of comfort. Setup was quick and effortless, and the battery life is as reliable as ever. If you’re looking for a quality trackball mouse, I can’t recommend this one enough! Read more

Replaced my previous model Logitech Trackball - can't read the model number but it was the dark blue type. This one is a bit stiffer than I remember my old one starting off as, but this could be just because my old one was falling apart more than I realized. Either way, it works well and is crisp with its responsiveness. Read more

Love this mouse and want a second one for my home office. So worth the money to invest in a good mouse for those who work at a desk. Quite, easy setup, Bluetooth setup a plus and easy to pop out the ball to clean when starting to stick. Read more

My preferred mouse control. Works very well and the ball is easy to clean. Read more

I do 3D design work and consider this trackball an absolute must-have. I spend anywhere from 8-14 hours/day working at my desk, with my hand on the trackball for large percentage of the time. The design fits my hand perfectly, with the buttons and wheel falling in exactly the right spot. Most importantly, it eliminates the fatigue, pain, and numbness that a regular mouse causes me. If you haven't tried a trackball before, there is a day or so of learning curve, but it's worth it! Being able to leave your hand in one place instead of sliding around the desk is something. Because it sits in one place, you always know exactly where it is on your desk. And once you've set up the speed to fit your taste, you can move from one side of the screen to another with the flick of your thumb. Additionally, it's very precise with slower, finer movement. I also find the connectivity with the dongle/adapter to be seamless. You will need an open USB-A port on your computer to use it that way or you can use Bluetooth if you don't. You will occasionally need to pop the ball out (just stick your pinky finger through the hole on the bottom and push) to clean out a little grime when the ball stops spinning freely. But it only takes a few seconds. My reason for only four stars is durability. I have to buy a new one about once a year or so because the left-click button wears out, but I probably click harder than I should, and I put a lot of miles on it. If you have a lighter touch or don't use it for as many hours a day as I do, it will probably last much longer for you. I view having to buy new ones as kind of like changing the oil in your car. The tradeoff with no pain or fatigue vs spending $50/year is well worth it. Read more

So I've been using Logitech thumb-based trackballs since they were rectangular and connected with a DE-9 serial connection. I swear by them and have converted many others. The advantages are clear: you don't need huge swaths of desk space to move them around, you can remove your thumb from the ball so you don't inadvertently move the cursor when you click, and the interface is extremely intuitive and easy to use. The biggest disadvantage is that they are solely right-handed -- my two lefty kids can't use them. The kids also say they're not great for gaming so that might be a factor; my youngest uses some specialty mouse designed specifically for gaming. As for this particular model, it's not terribly different from the previous M570. Note: in the pictures, the new M575 has the more silver ball; the one with the more blue ball is an M570. The forward/backward buttons (between the left mouse button and the trackball) are less prominent on the newer model and include indentations that appear to be simple circles. I'm guessing that the circles are meant to give your finger a reference point to be able to click without looking but I find them more annoying than useful (they feel like there's a piece of dirt or something stuck to them) and the prominent buttons of the M570 were easier to feel, as well as being less susceptible to accidental clicks. The palmrest part of new M575 as some subtle ribbing, probably meant to keep your hand from slipping from side to side but it's honestly just another annoyance. Not enough to prevent me from using it but given the choice, I would prefer it without. The activity light/battery warning light has moved from just behind the forward/back buttons to the middle behind the main mouse buttons. Not a problem at all, just different. I will note that the light on the M570 can be seen even when your hand is on the trackball whereas this one is covered up by your hand. The trackball itself is fine; I think I like the old blue color better but there doesn't seem to be any other difference. The bottom of the trackball is not functionally different from the old version and it's good to see that the slot is still there in the battery compartment to hold the receiver. The power switch is a little smaller and harder to access but still perfectly functional. There is a new button that appears to switch the trackball from using the receiver to using bluetooth -- a handy feature if you want to use it with something like a tablet, I suppose. (I've not tried it via bluetooth.) If you're thinking about upgrading from an older M570, you'll feel right at home, for the most part, but I don't think there's any compelling reason to rush right out and get one. I bought a new one because the scroll wheel on my old one stopped working reliably. Had it not, I'd still be using the M570. (Note: I still use an M570 in my office, as does my wife.) If you're new to this style of trackball, imagine laying your hand on a gently curved rest and moving your thumb around. It's comfortable and less stressful than a traditional mouse and it requires a lot less free desk space. It doesn't need any particular type of surface; I've used it with it on my leg, on the bus seat next to me, and on my bed. It's not the cheapest device in the world but if you're hesitant to spend $50 on a trackball, you're probably not a heavy or serious user. Gamers will probably look elsewhere and possibly even pay more; casual users will be looking for something in the $15-25 range. I'm in front of a computer 8-12 hours per day and I don't mind spending a bit on something to make that experience more efficient and more comfortable. If you want to try a trackball without spending as much, there are some decent knock-offs on Amazon that should be fine. But if you don't mind investing in something like this, it's well worth it.

Best pointing device ever made. Much better than it's rechargeable successor, which is a classic example of "fixing" what wasn't broke. Easy to remove & replace the ball, which is important, because trackball bearings need to be cleaned frequently and getting the ball in and out is the hardest part of that. The actual cleaning is just a matter of using your finger to wipe out the gunk and done in seconds. The more expensive "improved" version of this has such a tiny push hole you have to get a tool to get the ball out. A good one-shot battery lasts for months. Couple this with a Logi wireless keyboard and computer use is a lot simpler and less cluttered. Read more
