The ReliefBand is a watch-like device worn on the underside side of the wrist for use in the treatment of nausea and vomiting due to motion sickness. When activated, the device emits a low-level electrical current across two small electrodes on its underside. The ReliefBand is the first patented, commercially available Nausea-Vomiting device to reach the marketplace. Now with user-replaceable batteries!
