I bought 2 pans and the info says not to put in dishwasher, you are supposed to keep them oiled after handwashing. The don't seem flat in the middle and food slips to outer edge. Have to be careful storing them to avoid chipping. And yes they do mark despite being told they wouldn't and eggs still stick. They seem to take ages to heat up - not supposed to heat empty so not best way to cook some foods and don't seem to brown food very well. I bought them to avoid having to use additional oil when cooking but the info leaflet says to keep oiling the pans so can't win. Not quite what I thought they would be.
