When I unpacked the pan, she made a quality impression. But after the first rinse cycle in the dishwasher (pan is suitable for dishwasher), has been formed at the bottom of a dark gray layer. This layer also forms the dishes by hand. Is wiped with a cloth over it, this takes the "lining" on the most part. I assume, are here to an aluminum oxide layer, or any aluminum salts. Since aluminum is to be harmful in the criticism, I'm a little worried. I rinse the pan now only by hand, since I do not want to have in the machine the aluminum. Unfortunately, this was not the first criticism of this nearly 60-euro pan. The non-stick coating of the pan bottom has a brownish color after about five times fry.
Now I like to cook and also knows how to handle pans. I'm sure to have done nothing wrong. The non-stick pans from the discounter, however keep a good year with frequent use before they have the first signs of aging.
It annoys me a little that a "quality product" from Germany has such weaknesses.
