This just came in the mail, and I have mixed feelings about it.  The beads are larger than I usually wear, but that is always hard to gague from a website.  That being said, the elastic is a bit loose and already feels stretched out.  I needed this bracelet to be smaller (but I have small wrists - and the ad says 9mm).  I don't want to ding them for the fit.  However the eleastic band they use to make this one size fits all seems to stretch too easily and therefore not hold as securely and the coin that is "tied" to the bracelet also has this blueish substance on it (that looks like they glued it to the chord.  All that aside, I like the set up, and would consider redoing the bracelet.  But it would probably be easier and cheaper to buy a different one.  This is a near miss for me.  If you have fairly thick arms (i.e. wrist) this may work better for you.  If you are a lean individual like myself, it likely will not.
