It took a long time to arrive from China.  Comes with a pamphlet full of "engrish" phrased instructions and greetings.  I put the bracelet on my wrist and it falls off twice within the first 5 minutes.  The clasp will not hold. Pops open with the slightest movement.  Additionally the bracelet's size is not adjustable.  I added one star for the ease of returning this piece of junk.
