Just got it. Too soon to tell, as far as benefit is concerned. When received, one of the small, round, inset pads was dislodged and had to be reinstalled.
Heavy well built unit. Defiantly has enough power to over shake me. The remote is a nice touch. The only issue I have had is the plate mounted control screen has cracked and broken from the weight of a small child vibrating with me. I do feel more energy and have seen health issues improve.
