I would give this product 6 stars if I could. The installation was easy. The cooktop heats so evenly. I can keep warm, summer, and sear better than on my gas cooktop. I can boil 4 quarts of cold water in less than 2 minutes. The surface is easy to clean and is very durable. I love the fact that this product had knobs instead of those annoying touch screen displays. For the money you would be hard pressed to find a better cooktop.
