I bought these, expecting non stick, and I'm completely unhappy!  The warranty for return is useless as, it states that you can't use them and return.  That's ridiculous!  You don't know they don't work until you use them!  They look amazing, but, they stick more than a stainless steel pan with NO nonstick coating!  I used a pan twice to cook an omelette, and no amount of butter can prevent a sticky mess.  I looked at the warranty and it says it is voided if used.  Only unused pans can be returned in original packaging.  Buyer be aware!  I don't recommend buying these as a non stick pan.  They look good and probably for meats might be ok.  They just shouldn't be marketed as non stick.
