The mousefix has never really worked for me anyways
Update from me:-
Been using the same mouse since release. Some of the protection stuff rubbed off over the white bits (the spawn writing), but i rubbed it off and it's never got any worse. Nothings broke with my mouse, which sees a fair bit of usage.
As reported by some others, I'm fairly sure there is a small bit of angle snapping with it set to off. My circles have flat edges, etc. Lift off sucks, and I don't care what skylit says, tape fixes suck too bro. Solid mouse otherwise, one of the best.
