What are you waiting for? This is the trackball mouse you're gonna love!
By Da' Yeti on Reviewed in the United States on May 25, 2025
Why did I wait so long to go with the perfect trackball? Features I didn't even realize I would love!: - cordless! It charges very quickly, and lasts more than a week on one charge. - it feels solid! Two positions with a rubber grip bottom makes sure it doesn't slide around your desk or bed or wherever your pc is set up. - the bottom is magnetized, so it pulls right off to quickly access the track ball for easy cleaning! - since it is cordless, so easy to use it in all kinds of environments, and unlike a regular mouse that requires space to use, you need only the space that this sits in, to use. I use this on my counter while I'm cooking to change YouTube videos or Netflix movies playing on the side screen, and it has a great cordless range to the device. - it has the potential to hook up to several devices, so it's a quick push of a button to select the device, and of you go, rolling the ball and controlling the interface. My setup is a wide screen monitor hooked up to 3 different computers, I have a cordless Dygma Raise 2 keyboard that can connect to any of these PCs, along with this mouse that can also connect to any of the 3 PCs, so I have one keyboard and one mouse controlling everything on my desk. It affords the ability to have a clean looking setup, and I can't say enough how easy it was to learn how to switch between systems, and how easy it was to adapt to using a track ball mouse over decades of using a standard mouse. It's solid, easy to use, easy to clean, easy to charge, a real quality mouse that I'll have for years!

Input Ghosting for Mouse 4/5 and Scroll L/R
By Nicholas G. on Reviewed in the United States on March 13, 2025
Under almost every use case I can think of, this mouse does exactly as you'd expect. However, there is a fundamental issue with this mouse that I cannot abide by. The left, right, middle clicks and scroll function independently as expected, but the mouse 4, mouse 5, left scroll, and right scroll are all fighting each other. In keyboard terms, this is input ghosting. Essentially, If you hold any one of the 4, the other 3 will be nonfunctional until you let go of the initial button. If you think of typing, it would be like holding the F key and then pressing the O key. You expect to type "fffffo", but instead you just type "fffffffff". Granted, the cases where one would want to press both mouse 4 and 5 simultaneously is VERY niche, but this was not an issue for the Logitech M575, and I wasn't expecting it to be an issue for this device. Given that this device works for almost everyone else, but is unacceptable for me, I cannot give this the 1 star I would personally give it, since it's otherwise a 4 or 5 star trackball mouse.
