For years I have used this mouse, 3,000 hours of Arma 3, 700 of DayZ and many many more from other games. When the cable eventually breaks, I will fit a new USB, when the switches turn to mush I will solder in new switches.
I’m far from a fan boy, especially when it comes to Corsair but the Scimitar, best mouse I have had.
I just about always prefer repair to replacement. Even if I’m not in love with the thing, less expense and pollution is worth a little effort.
