At first I was very excited about the pans; According to Advertising Dishwasher safe, easy to stack and less oil or fat for frying - great! Unfortunately, the pans can not deliver what is promised. After a few weeks, deposits have formed on the floor, the pans bulge upwards and of a uniform roasting result one is miles away. Too bad, but for EUR 40, - (supposedly even original EU R80, -) I would have expected a little bit more. Unfortunately recommended in any way.
