Query: Excellent Product

I did a lot of research on the best stainless steel cookware and it paid off! This product is heavy duty, cooks thoroughly and evenly, cleans up nicely, and holds up well. My only complaint is that they didn't warn me that cooking spray would leave a stain if used in a hot frying pan -- but even that is worth it. A great product for a very reasonable price!
