Bought mine when I built a PC in ‘08. Another PC and two MBPs later, still use it daily for work. Had a scare recently, but took it apart, used compressed air on the little gaps in the middle of the scrollwheel and it’s back to 100%.

Not a fan that I have to use third party software (sensible side buttons) for the back/forward to work on MacOS, and still no idea how to make the expose button work again, but it’s still worth it to use this mouse.
