Logitech Ergo M575S Wireless Trackball Mouse, Wireless Ergonomic Mouse with Bluetooth and Encrypted Dongle, Comfortable Thumb Control, Precise and Smooth Tracking, for PC/Mac - Off-White Blue Ball 2024 Model White + Blue Ball

excellent product, and great for prevention of carpal tunnel in the writs. I love it and bought one for each computer I use (work and home). It can feel awkward at first but I got used to it pretty quick and I won't ever go back to a traditional mouse again

Logitech has been making trackballs for some time now. I have been using them for over a decade and with this newest model, the ERGO M575, they continue to improve the basic design. It now has a lower back enabling your hand to rest more comfortably on the top, reducing stress and improving circulation. The buttons are like older models, but they have been modified so that you need less pressure to make the connections. (That might, however, be because my other model was so old.) Transitioning from a nine-year old model that recently bit the dust to this one was effortless. There was no issue with the software and of course the design was practically the same but with modifications such as the height that make it easier to use. This trackball is sturdy like other Logitech products, so you can expect many years of use from it. For people like myself who have less desk space to work with, Logitech's latest standard trackball is a great solution which is much more economically priced compared to those from other manufacturers. I recommend it without reservation.

edit: I liked using the trackball so much I upgraded to the logi MX ergo and use the M575S for my laptop. I stand by everything I said here - but the MX feels better in nearly every way... clickier buttons, nicer plastic, smoother rolling, metal stand (except feeling a bit smaller in the palm and needing a pen to pop out the ball) however - it is twice the price, of course, but I would consider it. Build quality is great - good enough weight to stay put. Plastic feels nice, slightly grippy and semi-matte (not that shiny cheap black plastic you find on many mice). Buttons and wheel feel nice, but the buttons are on the softer, quieter side in terms of clicking (totally functional, just to know if you prefer a thick click). The ball is fairly heavy and rolls nicely. I am surprised how precise and fast it can be - so much so it takes some getting used to in addition to being a new way of moving a mouse for me. Still, it's definitely usable for most tasks while in the learning process. It's nice not having to change mouse sensitivity, instead doing it intuitively with the ball. The only issue is logitech's software. The mouse runs perfectly fine without it, but if you want the extra options just be aware that logi control is poorly maintained software that has an installation issue, apparently worse on macs, and I'm still jumping through hoops getting it to work on pc. For some it just installs fine, for whatever reason. To be honest that's kind of expected with hardware apps these days.

I`ve had this style of trackball since the mid 90s. The first I had was wired, the second, my first wireless, held up for 20 yrs. I`m now on my 3rd, solid track record. The compact space saver let`s you keep your desk cluttered without maintaining a safe space for a mobile mouse, so your best work performance is always at hand!
