I bought 2 because I always have a backup. I am a carpet fitter with over 40 years of experience. In the first year I would say that one of them was questionable and voiced my concerns, but I was willing to go along with it and do it in my support. Since then one or the other part has broken. It's like I bought the worst merchandise on port charters. Almost all problems are related to the lining and exist because it is made of very poor materials, that is, poor quality metals. When I asked Roberts if there was anything they could do about it, they ignored me. For real? Such an old reliable company? Come back to Crane for me!
