I had one of their non-beadlock pintelers cracked, but they replaced it under warranty. I have since sold those rims and am now running Slabs.
Another member here just recently ripped the weight lip off the outside of his Pintler after catching it on a rock (not that big of a rock).
I have seen a few threads where folks with the beadlock versions have issues getting the ring to seat correctly. It is pretty thin and can warp during install.
