I dunno, I had a single experience with Corsair recently and it went pretty well
Corsair Void pro was having issues where turning the volume knob on the headset would create crackling noises in the earcups.
I emailed them about it and within a day they sent a RMA slip and I shipped it out and got a replacement in ~3 days
For my first RMA with anything ever, it went pretty well
EDIT: Also I had my microcenter receipt as well, so
