I have two copies of this pan, purchased at the beginning and end July 2009. The Amazon specimen showed very soon clear Discoloration of the coating, adhesive-free frying was barely possible, although I am exactly at the instruction manual held and only use plastic spatula. My first Pan, however, is still in fine fettle. It has indeed the impression that if it were two fundamentally different pans. And if I precisely the coatings take a closer look: differences in the structure are in the Indeed, clearly visible. Where does Amazon only these pans ???
