I purchased the square, high sided pan. Best cookware product I've ever had! Nothing sticks. Some people have said they used non-stick spray, but the instructions clearly state to NEVER use it. I either use nothing or a teaspoon of oil, depending on the food I'm making. I do use a tiny dab of butter for eggs. That's just taste choice.
Since of the directions say not to use pointed things, and I don't use knives or metal turning forks, but I've used metal utensils, plastic, wood, you name it. No damage at all. In the month I've had this pan, there are only two days I haven't used it, and it's in perfect condition. No scratches, no warping, nothing.
Also, I've been washing it in the dishwasher with perfect results. Just read and follow the directions for perfect results. I'm going to buy more Gotham Steel pans. Love this stuff!
Bottom Line: Yes, I would recommend this to a friend
