Query: Nonstick Coating Wears Off, Company Blames Customer, Voids Warranty

I was really happy with this cooking set for a good number of years. So happy, in fact, that the 12" Fry Pan became my favorite cooking pan. As a result the non-stick wore off under the normal course of its lifetime.I was able to get an RMA for the pan, but it was returned to me with a letter stating that the browning on the pan indicates that it was subjected to overheat and as a result, the pan will not be replaced.Problem is, there is no browning on the pan, and I've never overheated that pan. It runs at one temp and one temp only on my range and never empty.Do NOT buy this set if you expect, as I did, that the company will stand behind their product. In fact, I'd stay away from Emerilware, T-Fal, All-Clad and Cephalon as the letter sent to me indicates that they are all the same, extremely non-customer focused, company.
