The Circulon 10 piece hybrid stainless steel pots and pans is a very solid and sturdy design. The base is built heavy and cooks on a lower temperature than I was used to at first. That’s because it heats everything evenly. I tend to cook with butter or olive oil, but even without it has a nonstick base. It does say not to use cooking sprays on the surface. They were also easy to clean up afterwards. I am happy with the set.
