I see commercials for these every now and then. It is some metalic braclet that someone where that grants them some special energy or something. I cannot make out what exactly it does because the commercials are so damn vague. The commercials consist of people just saying how great the bracelet is and how it changed their life. Then they go into how some athletes wear them and so on... I am very skpetical of a product that does not reveal the mechanism by which it does what it does, much less not revealing what it does at all. Does anyone know about these? Is there any scientific evidence that backs up the ability of these bracelets to do whatever they do?
