This Circulon Symmetry Hard Anodized Nonstick 11-Piece Cookware Set in Merlot has a lifetime warranty and is great quality. I use them on my gas stove and the food temperature stays evenly distributed. I use metal utensils and they don't scratch the non stick surface either. They are even great for cooking in the oven. I love that I can put them i the dishwasher. I would highly recommend this set of cookware.
