I came across a device on line manufactured by The ReBuilder Company in West Virginia that claims to offer "electronic nerve regeneration, healing impulses rebuilds your nerves, increases blood flow and strengthens your calf muscles". They offer what appears to be impressive endorsements. Has anyone heard of this item, or better yet tried it? It carries a pricey $699 cost and I'm wondering if this device is nothing more than snake oil or does it have some real value. Anyone??
