Rated 5 out of 5 by from One knob control is a genius design. One knob control is a genius design. In comparison, any design with a bunch of hard-to-press buttons is a terrible design. You may ask, with one turn knob, how does it control power level. It turns out you do not need lower power level if the heating can be uniform. Lower power level is just a patch up for poor heating uniformity. This microwave can magically heat evenly without a stupid rotary plate. Just genius and elegant design!
