The most expensive model of Tefal is not the best one. The bottom is warped in the center, the oil doesn't stay in the middle and spreads around. This is a common issue with most pans, but when you buy an expensive pan like Tefal, you expect a coating that can withstand the use of a metal spoon. Forget about it, all types of coatings, whether ceramic, stone, or simple, get scratched to some extent. If you want something that doesn't scratch, forget about non-stick coatings and get a stainless steel pan instead
