Supposedly this microwave is the only one with the revolutionary "Inverter" which produces power differently than other microwaves. All other microwave ovens, if you set them to Power Level 5, pulse on and off at 100% power. Panasonic's new microwave outputs the selected power level 100% of the time with no pulsing. They claim that this results in better results, no overcooked edges, etc. They say you can actually keep it on Level 2 continuously and food will stay warm without overheating. Anyone have one of these?
