I've bought a few over the last couple of years, and for the most part they're pretty nice knives. Some are definitely better than others. You'll find issues occasionally, for me it's been the grit (polishing rouge) in the joints. Once that's cleaned out and the knife is oiled, they're usually pretty nice.
Case is a better brand, IMO, but I've had issues with two that I've bought in the last two years, each time with scales. With Case, they'll fix it, no questions asked, as long as the knife doesn't look abused. The sellers for RR will usually just send a replacement if something's wrong; at least that's been my experience.
