I have been using Granite Stone 20 piece cookware & bakeware set. They are beautiful and very heavily made I replaced all my other pans and bakeware stuff. The only thing that might be a issue is it’s not like a smooth surface so I’m hoping that it won’t be a issue later on. I don’t believe it will cus they are so heavily made. I do have to say they don’t bend or like pop when cooking like some other brands do when they heat up. I do give them 5 stars cus I’m so impressed with how heavy duty they are. I do recommend these to family and friends.
