I spray-painted a cheap mouse that came with my laptop (it looks messy but in a good way?), and the left/right clicks miraculously worked after a bit of work (the left clicks is actually a bit dampened now, making it quieter!)
However, I think the optical sensor is borked. The mouse can click but it can’t move the cursor.
I’m thinking something like a bluetooth motion tracker that moves your cursor could work if I mounted it on the mouse, but does something like that even exist? I searched online and it doesn’t seem to be a thing. Maybe I have to DIY it a bit by buying a bluetooth motion tracker and using a program that makes it so that is moves the cursor?
You may have seen the other reply, but the screws are probably under the little pads under the mouse. You peel them off and then glue them back after.
