Let me start off by adding 2 disclaimers. 1) Anybody who believes ANY cookware is 100% NON Stick is delusional. Unless you're cooking on a cushion of air, there will Always be an issue with sticking. 2) The claim of No oils or grease is a little inaccurate.
That being said, the cookware performs as expected and advertised. The first thing I tried to cook in it (after proper seasoning) were chicken breasts that were floured, egg-dipped, then floured again. With NO oil, the flour burnt on the bare pan. I added just a little bacon grease to the second pan and continued with dinner. The bacon grease solved all the burning problem. I only used about a tbsp of grease in each pan and my culinary world was good again. Because of the superior heat dissipation of this cookware, med heat should be considered "high". I reckoned it to cooking on gas. Turn down the heat, and add minimal oil or grease and the pans performed flawlessly.
As to sticking, I couldn't wait to try eggs. My girlfriend likes her eggs over easy. The very outer edges of the eggs initially stick, but the slightest of force possible broke the edges loose and afterward, they slid around the pan like on TV. The plastic spatula slid under them and they were a breeze to flip. I really did slide them from the pan to her plate without any utensils.
Nothing in this world is Perfect. Don't expect Perfection and you won't be disappointed. This cookware is amazing so far, looks good, and is a joy to clean. I have never had mine in soapy water yet. After cooling to room temp, warm/hot water and the dish cloth or a paper towel clean it to out of the box condition with almost no effort on my part. in this respect it is better than any teflon pot or pan ever made.
Since I have only owned mine for about 2 weeks (but used every day) I cannot yet speak to the problem of staining and sticking after time. I will also say that the only utensils that have touched this set have been made of wood or plastic.
If there are any House, M.D. fans out there reading this, remember one of his "House-isms", "Everybody Lies". This is, as we all know, truer in business than in personal life. All companies represent to the high side their products. Perfect? Surely not, but a Very satisfactory product, and unbelievable for the $119 price tag WalMart has on the 10 pc set.
I will order the 12" skillet, if I can get the lid for it, as the 10" won't allow a full strip of bacon to lay in the bottom of the pan fully, and the Flip Jack pan is a definite possibility. If it performs as well as the rest of the set, I will be completely satisfied.
I will recommend this to friends with the two noted warnings above.
