I purchased 2 of the square pans. I use them for Filet Mignon , followed directions in Copper Chef cookbook. Do not cook from frozen, all you add is salt and pepper. I do Orange Roughy, just salt and pepper, add some butter of top, follow cooking instructions. I just baked a cake in one, use heat and time for Bundt directions. Made French fries. I have used these over and over, they look brand new. I hand wash and hang from handles. I have never had anything stick or stain these pans. I have only used cooking oil and butter. You must follow directions with the cookware, you cannot abuse it.
Bottom Line: Yes, I would recommend this to a friend
