Bought a used #Kensington #Orbit #Trackball with Scroll Ring a couple of years ago for testing instead of using a classic computer #mouse because the surface of my Microsoft #Intellimouse Optical from ~2000(!) finally went goo: https://www.reddit.com/r/nostalgia/comments/jpiv8p/microsoft_intellimouse_optical/
#OrbitTrackball: Love at first use. And it's #ergonomic and not wireless.
Unfortunately, this week one of its buttons started to act weird so I just bought a new one as a replacement.

I can totally recommend that thing.
