After all the positive reviews I just had to order these pan. And what can I say, she's really really good. Although the baking pan caused a lot of smoke, but it is worth this process so that you get a nice skillet. In other pans of de Buyer one reads sometimes even that the pan bottom is not flat, which is not the case with the I ordered pan. This has but in my opinion nothing to do with a poor quality control but is due to the expansion coefficient of the material and so desired by the manufacturer. The second of de Buyer acquired pan (32cm) is also not plan and works the same as the first on a ceramic hob properly. In summary, one can only write, that's a great frying pan at a more than fair price.
