Circulon is the best cookware in the marketplace.  I have owned many different brands and Circulon outbeats them all with the best quality and craftsmanship.  Their pans have a center temperature heating core that heats up the entire inner surface of the pan evenly as well as the pans are well balanced and stay put on the burners of all stoves without sliding off the burners.  I have been using Circulon pans for the past several years and my last pans used to be Calphalon as well as Anolon, which I felt were the best until I found Circulon.  When using these Circulon pans you can cook without overheating or burning your food as the heating core stays at an even temperature and cooks your food without burning or sticking to the pan.  Cleanup is easy if you watch how you cook and I find it very easy just to use a sponge with soap and hot water.  I have pretty much replaced my older Calphalons and Anolons with Circulon.
