What happens is that two crystals strike each other creating a slight, harmless tingle of electricity that stimulates your body's own natural pain-blocking response. The unit requires no power source or batteries and is always ready for use. You may have seen Evel Knievel on TV advertising this device. Also effective on acupuncture points. However, for the normal person with aggravating pain, it is a miracle as was attested to on TV, and in our own personal experience.
