Actually, there was a lot customers could ask. First, why in the world do you need yet another way to heat food? Kitchens already have an oven and range, plus perhaps a toaster, waffle iron, or a grill on the back porch. And the coffee pot can keep coffee hot anyhow. Do you really need another oven? Plus, surely it won’t work quite like an oven, or quite like a stove. It’s like something in the middle. How could we need that?
