No I'm blinking not -for a start some bread will not fit in it and then other times you wait what seems like half an hour for the toast to get brown and other times you turn your back for a second and the toast is nearly on fire. I think they are actually an alien life form sent down to aggravate humans to death.
Toasters need heat proof monitors to watch each square inch of the bread, both sides and adjust areas of the heater to ensure an even browning, which stops the moment the set brown level is reached. Alterable on a per slot basis of course, and presets storable under the names of each of the family. I think that is still decades into the future :-)
