If I could give Thane Inc, manufacturer of these pans, it would be a no stars! I called them to warranty the two pans I bought because food is sticking to them. Customer service rep hangs up on me! I called back 5 times, and get disconnected. Called corporate office and the US office and nobody answers the phone! Do not buy these pans. They don't last and corporate intentionally does not want to warranty the replacements!
