While the heating elements themselves are efficient, the controls are terrible. Controls are hard to see, they should be backlit at minimum. They are unreliable, a piece of food dropped on them, a hot pot passed over them, or a casual swipe of your hand can alter settings or turn them on or off. You have to lock the controls after every use or cleaning the surface or placing items on the stove can energize a burner. I do not recommend buying this appliance.
