I had to replace our 3 quart saute pan. You can see that the non-stick coating is failing.
I brought the pan to William Sonoma and they did give me some resistance. They said that the damage was typical of excessive heat.
Thinking about it, there's a possibility that that may be true because we've now been cooking with gas for about eight months, whereas our old electric cook-top did not seem to give off that many BTUs.
I've had to replace various pans before, both All Clad and Calphalon. Laurie thinks I may be scamming the manufacturers, but I figure a lifetime guarantee is a lifetime guarantee!
