It is a pretty simple piece of equipment. It shouldn't be hard to manufacture a toaster oven that works. It's not a car, or a computer, or the Space Shuttle. I use it only to toast. It has decided to turn the heating elements on and off at its whim. At this point it's more off than on. It definitely warms the bread, and toasts it half way if you wait long enough. It was actually a nice toaster oven which I really liked before the elements started turning off capriciously.
