Do these beautiful heavy and very well processed pan now for some time every day they phase out in operation and superior. After a short time, some places discolored on the non-stick coating and are no longer got the pan clean. It has lost much more and more and so went the non-stick property. While you can still work with it a lot of fun but does not do that. Overheating should actually almost can not at 450 ° C - but that is what appears to have happened. Although as there are very attentive. "Green" with me is just a tool or device, if it lasts longer than the others and thereby its properties does not lose. Every 2 years, a pan is to throw away most definitely not "eco" and not cheap. I am now changed to Silit with ceramic surface and so far satisfied.
