While working a Bionic Band vendor booth at the Country Thunder Music Festival last April, the Zac Brown Band stopped by to check it out. They were impressed with the immediate increase in strength and balance when wearing the Bionic Band. All of them wore Bionic Bands during their concert, and sent a huge crowd over to our booth after mentioning the Bionic Band at the end of their show. Zac Brown told us his knee pain went away after a couples of minutes of wearing the Bionic Band. Later in the evening, several crew members from Great American Country television stopped by the booth, after hearing about the Bionic Band from Zac Brown backstage. They too were very impressed with it! The first picture is Zac Brown right after putting on his Bionic Band, and the other two are more recent pictures of Zac Brown still wearing his Bionic Band!
