I have to say GO Rachel Ray! This is the best set of baking pans I have ever owned. I don't usually purchase products designed and sold by celebrities, but this is one purchase I was extremely pleased to have made. I have been using these pans on an almost daily basis for over 8 months and they are still working great (no warping like other pans I have purchased in the past) and the clean up is amazing, just wash with soap and water or wipe with a damp towel.
