Corsair's was the only RMA I've ever requested. They were pretty fast. Fast enough for me; I'm just happy they have a lifetime warranty and can be RMA'ed years after they've been bought. And there were no questions asked; I just sent it and it came back a little more than a week later. I don't know if they're all this painless, but my hat's off to Corsair. I sent it out I think on Thursday the 16th (of November) and it came last Monday, the 27th. I seemed really fast though because I was on vacation practically the whole time.
