I used one quite a while ago. It used capacitors to adjust the apparent power factor so the old fashioned meter would think the old fashioned fridge was using less power. I timed my meter with a stop watch, and there were decent results. Later, with a newer, more energy-efficient fridge, I could detect almost no difference. I am about to get a new "smart" computerized meter, that will probably make it all moot, anyway. I suspect it will also make by bill higher.
