After 2 months is the "non-stick coating" in 1/5 of the pan on the floor in a "bond coat" over. I have maintained the pan always following the instructions. I have now complained at WMF. However, this is also quite an experience. On the WMF side there is no such thing as RMA. Then I called them, and they told me that I should return the pan easy unfree. But I do not believe! I now geandt me WMF email, response is still pending. If you do not respond to 4 days from now I have to stop on Amazon Reklamieren what Amazon yes, but also does not want to. Well, like all halt, Buy yes, then bye.
