The Ergo M575 is Logitech's thumb-operated wireless trackball, a follow-up to the long-running M570. It keeps the sculpted right-hand shape and adds Bluetooth Low Energy alongside the USB receiver, so it works with laptops that have no free USB port. The ball stays put, so the hand moves less than with a conventional mouse, which is why it appeals to people with wrist or shoulder strain. It is a mainstream, reasonably priced trackball rather than a premium one: the ball rides on static bearings, not the smoother roller bearings of pricier models, and there is no tilt wheel or horizontal scroll.

Owners rate the M575 highly as a comfortable, reliable entry into trackballs, and many use it for years. Complaints centre on the ball's friction, the right-hand-only shape and the lack of a tilt wheel.
