They are thin and deform at 400 degrees. I was expecting a heavy-duty, professional-grade non-stick product. Not being part of the Signature line, I knew they wouldn't be metal safe, but I was fine with that until I found something better. Now that the Calphalon Signature bakeware is showing up, I plan to try a product or two along with a commercial line of products. it only costs $1. Update: when I clean them in the dishwasher there is usually rust on the surface of the pan that needs to be washed off. I am leaving a 3 star review. I use them but definitely not the quality I expected.
