When I bought this for my wife, I had no idea how it would actually work. I just thought it would be a cool vibration for relaxing maybe shake up your lymphatic system maybe loosen up the facia but you stand up on this thing and it gets gone and after not even a minute, you feel like you’re doing strenuous exercise and I can’t figure out how that works. I’m gonna have to look it up, but that’s a really cool upside for this product.
