The Magic Keyboard 2 is great, but their mouse has given me nothing but wrist pain and infuriating muscle-memory issues. I still believe its flaw was being designed for appearance first and ergonomics/usability second, but no doubt I didn't give it enough time. Do you recall how long it took you to get used to it?

(For about 10 years, I've been using a bog-standard, symmetrical, 2-button scroll-wheel mouse by Logitech, and am looking to transition to a finger-operated trackball to save desk space, and just to see what the fuss is about.)
