These are Hard Anodized pans, and they don't use Teflon. I've got this set of Circulon pans from Costco [1]; absolutely no problems and my friends have been equally impressed with the non-stick properties. You can especially see it when making something like scrambled eggs where the egg just doesn't stick.
