I bought the VT007 and use it at the lowest settings. Who knows! I appreciate the honesty of the owner and found his website to be quite informative in general about vibration plates and research related to osteoporosis. He also answers questions, general and specific to VT007. Of course it’s all part of good marketing….who knows, maybe the VT007 will help me (I’m not holding my breath but at least I didn’t sink a lot of money into it).
