Such hard work put into this set. It almost reminds me of cast iron its so well made, without having anything stick to it. It says you can accually use metal in it but not pointed pieces like forks and knives. And the clean up is so easy, sauces and eggs and noodles and meats, none of them stuck to the pots or pans when cooking or washing, so easy without the grease. The 2 things I must point out is before you clean and use the first time, there is a round sticker dead center if each pot and pan. I thought it was part of the pan or pot, Its not, its just a sticker so peel it off. Also make sure and grab handle on the hard plastic part not the outter edges where the medal is at, as its hot there. Also have to give a big A+ on the lids, no area for water to get into, made so fantastic. Also the fact you can use in the oven on temperature below 400 is awesome.
