Like stocking said, I can only see someone really use these mice if they're into competitive games like Dota 2, League of Legends, etc.
although for people like me who just pay casual games and fps games, a normal 2 button+scrollwheel mouse is enough for me
it's all crusty for some reason and i don't know why
i think my hand flesh attaches to it
This is the same thing that happens to me.
I DONT KNOW HOW TO FIX IT.
