It's alternative medicine machine, which will be obsolete, when Obama-Care (less) kicks in (2013, I think). It's not for zapping the patient, but parasites, we are all infested with, which is why we are in such poor health, and why we need insurance... Hospitals don't save lives, insurance companies do.
But seriously, alternative medicine works on faith. Stress does a lot of bad things to the body, if you relax, and feel good, you will have better health. Other than stress related, if you have an infection, you need medical treatment. Anyway, it's not an expensive, or complicated circuit, low voltage, and basically harmless, if used externally...
