My Review for 11-Piece Hard Anodized nonstick cookware set is that they are definitely made of great quality. I have been using these for about 3 weeks now and i mean using them everyday for everyday cooking. So far there isnt any burn marks on the bottom and the nonstick hasnt peeled off or wore off. Im impressed with them so far. My o ly complaint is that they run a bit small for my liking.
