I've had mine for a year or so. No problems have turned up at all. It is a pleasure to use. I have several RRS brackets of different types for my camera collection; and I use a RRS QR plate atop my monopod as well.
I have found the company to be responsive and friendly at all times.
I seem to recall, however, a recent thread here about some problems someone had here with, I think it was, a BH40 ballhead. In the interest of full investigation, perhaps you could search for that thread and/or that person will chime in again.
