I had a 1gb stick go out on me last month. I filled out the RMA form, mailed Corsair the broken stick along with the other stick from that matched pair, which was still working, and Corsair replaced both of them with a brand new matched pair for free. That positive RMA experience coupled with my recent issues concerning the 8gb of G.Skill I just picked up has placed me solid into the Corsair for life category.
