The Thundervolt zapper has a new webpage at http://www.zapper-zap.com. We now have a Body Tester, which documents and verifies the level of your personal body power, chi, or life force. If you use our Body Tester before and after you zap, the calculated result number should rise. This will prove the effectiveness of zapping. Without the Body Tester you don't know if your zapping is beneficial or not. We are the only zapper makers that offer a Body tester. It's easy to use and inexpensive.
Thank you.
