The lights in my wife's laundry room used to blink & flutter when the washing machine was going. One quiet line on the same outlet as the machine brought it down to a barely noticeable flutter. They do work. I also put one on the fridge (obvious place) and directly on the AC recipticle where the amp plugs in. Definite improvement on the amp, primarily in the midrange textures and dark backgrounds in the highs without any compression of dynamics.
Enjoy,
