These are the best pans I've ever used. I upgraded from Circulon and the difference is amazing. Food tastes better and cooks more quickly and evenly. The pans are easy to clean too. For discoloration I use a bit of vinegar and they look brand new again. The only downside is the pans are heavy. I would highly recommend this set to replace all of your pans at once. I wish it also included a 1 quart size.
