 how this is compared to a rice machine. Most rice machines out there are either too expensive, too old, too difficult to use, or too low power output. Other rice machines, the method they deliver the frequency to the body is through electrodes. So you have to stick these pads to make physical contact and what they're doing is just sending an electrical shock directly to your skin. It's like sending one little stream of water onto your hand, whereas this coil is like bathing in a whirlpool of energy. So that's the difference between most of these other rice machines and g-coils.
