I would agree with you, but I still want to own a microwave. There are none with reasonable UI behavior as far as I can tell.
(Edit) For example: Opening the door a few seconds early always leaves time on the display which should just automatically clear after a minute or two. Obviously if the user doesn’t use that leftover time immediately then they aren’t going to.
Looks good actually.
But how does it handle the door opening early? Does it still leave unused time sitting on the time dial?
