Power Balance Admits Its Success Is in the Mind, Not Science

Power Balance LLC, the company behind a wildly popular line of wristbands and pendants worn by professional athletes (who swear by their performance-enhancing effects) admits its marketing claims aren't backed by science.

The ads declare that the silicone wristbands, which come in five sizes and 16 colors, optimize the body's natural energies and improve balance, strength and flexibility. Citing ancient Eastern philosophies, the company says the technology was "founded" by athletes and is a favorite among the elite sports set.
