I purchased this item last year. At first I was extremely pleased, but after less than a year the TransTherm base separated from the pot. Since was still under manufacturer's warranty and I had always used it according to manufacturer's instructions, I contacted WMF America. I contacted them several times via email, but only got the run around. Finally I contacted them by phone, only to be told by the customer service rep that this rarely happens and when it does it is rarely covered by their warranty. However, if I wanted to ship it to them, they would be happy to look at it and then tell me they would not cover it. I contacted the CEO of the American division and never received any response at all. How disappointing. They clearly do not excel in customer service and do not stand behind their warranty.
