The Body Back Vibe is a variable speed electric massage tool that delivers a smooth, stimulating, and effective vibrating massage. The Vibe's powerful vibrating movements can boost blood circulation, overcoming muscle pain & fatigue. Thanks to a dual-speed switch, you have an option for a lighter or more penetrating massage. Vibration from the Vibe calms muscle tension and spasms so you can recover quickly and hit the gym earlier. Do-it-yourself massage therapy with the Vibe can save you from the expense of a professional.
