I had been looking for a design of this sort for years for my gas stovetop and had not found anything until by chance I saw this website. Immediately, I purchased two and they are tempering the high heat of even the lowest settings that were consistently scorching the food. Now I can even keep stuff warm, without shriveling it! There is one thing that I can fault them about, and that is they are not quite wide enough for 20" pans and over, so the pan has to sit offside on the plate, which is a bit dangerous. They actually need to be bigger, or the handle needs to have it's hinge set away more from the plate to allow the pan to be centred. My spouse was concerned that the handle would get too hot, but it doesn't get hot at all. Any spills on the surface need to be scrubbed off, otherwise they get set on with further heating.
