Two hours after I put the bracelet on, it broke!  The most strenuous thing I had done while wearing it was drinking a glass of tea & checking my email.  No snagging or pulling - I moved my arm & it fell off!  One of the pins fell out & I'm hoping that I can get an extra one.  The bracelet was not adjusted & fit perfectly out of the box.  It was not misused in any way before it broke.  It looked great for those two hours!
