I also bought extra pieces but used one from this collection.  I was cooking up breakfast sausage.  The pan got like crusties when I was done browning and cooking on top of the stove.  I had to really scrub and even, that was after I used dawn scrub solution.  So I am still out on loving.  Sorry but I am also not happy with the lifetime warrantee.  If it is so durable, (doesn't lose the no stick even after thousands of sandpaper scruffs)why do I need to put anything in between the product but can use metal flippers etc.
