For years I used this type of stove, but they must be changed from time to temps.Quand I saw ceramic stoves I rushed. I was extremely déçu.Elles do not grasp and turn black. I returned to Tefal pans that satisfy me. I insist on the TEFAL brand. I have tried other, sometimes much more expensive, but which are far from the claimed. A well known brand sells such items the release layer is removed by large flaps when they are used.
