Exactly what I was looking for: a microwave design but also very easy to use: there is the button time to turn and it starts and stops by itself alone. He re-rings regularly if no one picks up the content was heated. The interior light comes on automatically when the door is opened. The bottom button sets the power (thawing 800 W). Once set, it is left over.
FYI: 2min20 to heat a cup of milk (which comes out of the fridge).
