Logitech M575 Ergonomic Wireless Trackball USB Mouse, Black (910-005869)

⭐️⭐️⭐️⭐️⭐️
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!

Latest incarnation of an absolute necessity
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.

First one lasted 2 years, 2nd one only 2 months
I really like the trackball unit as it is comfortable and fairly reliable. It requires quick cleaning of the ball “eye” inputs now & then, but is fairly reliable. This is a replacement of the same unit I bought 2 years ago. The wheel failed on it. It does get a lot of use though I am not a game player. So two years seems like a short life, but like I caid, I like the trackball for comfort and performance.UPDATE 11/2023: Only 2 months old (and 11 days after the return window closed) and the unit is frustrating sometimes as it refuses to react to the trackball movements or mouse clicks, even after replacing the battery and cleaning the “eye inputs” w/alcohol. Banging it on the desk restores it. Not very good quality IMHO when it requires banging on it to make it work. Sorry Logitech, but you made a POS in this one. I am forced to buy another one, a Logitech again as all the others reviews scare me. My opinion of Logitech just fell considerably.

Benutze sie schon einige Wochen und bin sehr zufrieden.

Simplesmente excelente!! Como perdi tanto tempo usando mouse convencional? Comprei para diminuir as dores nas juntas dos dedos e no pulso, e após cerca de 10 dias usando já diminuiu bem as dores, só tenho um pouco no ombro, mas é por conta de não usar cadeira/mesa adequadas, quando trocar a cadeira acho que resolverei isso. O mouse ser sem fio já melhora bem em relação aos que possuem fio, e a conexão é super prática com o adaptador USB ou por bluetooth no notebook. O Tamanho e a ergonomia são excelentes, e a posição é bem confortável, não senti dificuldade para adaptação, liguei e com poucas horas já estava usando tranquilamente para as tarefas comuns. Para edição de imagens que exigem movimentos precisos levei cerca de dois dias para dominar completamente, porém acredito que o trackball seja muito mais preciso que mouse comum, após a adaptação tenho essa sensação. As teclas de atalho pré configuradas para voltar e avançar página de internet ou pastas do explorer são muito úteis.Só satisfação com o produto por enquanto, em breve vou adquirir um teclado sem fio da logitech também para usar junto, mas por hora recomendo a todos, principalmente para quem nunca usou um trackball, acho que é bem melhor do que o mouse convencional
