Hunter Mahan and Ricky Barnes wear one. So do Clay Mathews of the Green Bay Packers and Matt Kemp of the Detroit Lions. Soccer star David Beckham has also been seen sporting the colorful silicone wristband, as has Great Britain's Prince William, who flys rescue helicopters as his day job.

Thery are just a few of the elite athletes who have added the Power Balance band to their arsenal of high performance equipment ... So what's the deal?

The company was founded in 2006 by Josh and Troy Rodarmel, two brothers with a passion for competitive sports. A top high school high school quarterback, Josh chose to attend Yale, but injuries kept him from ever taking a snap on the college gridiron. However, he remained focused on athletic performance, and how to achieve optimum performance. Together, he and Troy began exploring ideas - and came up with the small hologram that is embedded in all the Power Balance products.

According to the company website, the core concept behind Power Balance is to "blend the powers of Eastern Philosophy and Western Science with innovative technologies to deliver products that improve and enhance people's lives."

Does it work? Mahan claims it gives him an edge over the competition and that after starting to wear one in 2010, he began playing the g best golf of his life. He now says he won't hit the course without one. So what about weekend warriors? A friend, who is a 15-handicap recently told me that after slipping on one of the bracelets, he went out and shot a career round 79. "I won't be taking it off anytime soon," he added.
