I bought these direct from Tirechains.com a few years ago. There are no issues with them as a company, I have bought many wheel chain sets from them over the years. I included them in the order because the concept seemed simple. Unfortunately, the first time my Envoy got stuck on ice, I put them on and they fell apart completely. They are not very well made and do not withstand loads (e.g. when trying to unhook the car).
