My Steelseries Rival arrived today and what I've immediately noticed is that the left and right mouse button actually scrape against each other when both pushed, making aiming and shooting a little more tricky than it needs to be at times. I'm tempted to get my girlfriend's file out and file the LMB down a little 'cause I'd really like to avoid the whole RMA process if possible.
Has anyone else experienced this? What do you guys suggest?
Edit: I just want to add that the ergonomics on this mouse are gorgeous - it's the firs thing I noticed when taking it out of the box - and the no mouse acceleration is phenomenal for FPS. The sense of control it gives you is second to none.
Edit: I've just noticed that holding down either mouse button and using the scroll wheel will cause the wheel to scrape against the button as well. It doesn't hinder any movement, it's just friction where there shouldn't be.
