TireChain.com replaced the crossed-up chain fast, absolutely no hassle and excellent customer service--everything was easy and ready to go before the first snowfall. The return did get lost on the way back and they asked for a bit of help on the send-off, and that was it, the carrier "lost it" for a week and then delivered it unexpectedly (certainly not the fault of TireChain.com).
Compared to ladder chains the ride is much smoother, though they'll still beat the hell out of concrete if going too fast. Also, there's no sliding downhill sideways and into trouble with the Euro pattern, which for me on ice with rocks and trees to slide into is important.
