I purchased this set in December of 2005. By the end of 2006 the "non-stick" coating had begun to chip off. I took extreme care with these pans, using only nylon tools and hand-washing them. I have since learned that non-stick coatings may be toxic. I have wondered for years if Teflon (or any non-stick coating) that flaked off into my food was toxic. Now there is increasing evidence that it is. So I threw out my KitchenAid set and am looking at purchasing a new set of stainless steel.If I could give this product a -5, I would.Live and learn...
