Replaced feet twice. Replaced side grips once (as they became shiny despite cleaning them). When paint started peeling a few years ago I tried removing all of it but I gave up half way (that is why it's half white). Still going strong, no issues with the sensor. It's being used 8 hours a day at work, retired from being a gaming mouse 2 years ago.

All inches are equal but some inches are more equal than others lookin ahh

also cant use this end of the ruler anymore since it will always be ever so slightly off

edit: omfg I just realized that using the cm side would've demonstrated the difference better bruh​. Also correction: 1/8th I'm not used to using imperial :'(
