After a few weeks, the first good impression is something sensational perspective. The cleaning was possible already after about 4 weeks only by normal rinsing. When roasting, there was at that time already more buildup than with an equally old Teflon pan. There have been first discoloration of the surface, which could no longer be removed.
Today, after about 9 months of use, I'll throw the pan. The coated area now has a large number of rigidities that no longer can be removed by scrubbing. No matter what you now prepared in the pan - it sticks! From a non-stick coating has an adhesive coating. This can not be avoided by a greater fat addition.
Conclusion: If you on principle exchanges his pans every three months, which is very well served by the Kerama Biolux. All others I can only advise against the purchase.
