Optical me the pan like a lot. Initially, the non-stick effect in the coating was very good. After a few weeks of non-stick effect already abated, however. Meanwhile, "potatoes" to burn only or stick to the pan bottom, even if I spoonful OIL deliver them into the pan. Too Bad. I bought three pans in three sizes, can these three "pots" use only as "pots" (z. B. to vegetables to dampen with water), but not for frying.
