I just bought my deathadder, ive used it pretty much everyday for the past 2 months and now the scroll wheel is super squeaky, anyone else have this problem and know how to fix it?
No problems here with my DA2013.
You probably got some dirt/hair inside where the wheel sits on it's axis. The only way to fix it is to clean it and then reapply some grease. But that means opening the mouse up.
If it's under warranty I think you could get a replacement.
