For starters, you should check my review of the "Light-Up Flashing Star LED Ball Pendant Necklace", noting they come from the same place.  Much like that review, the product is MUCH larger than it appears in the photo.  This is not a small ornament, but rather the size of a Christmas ornament.  Who is going to hang something that large around their neck?!  Granted it does light up and do assorted light shows, much like toys one would find at a theme park, etc.  Knowing its unwieldy size, and that the batteries are located in the item and not in a barrel clasp, I decided not to give this as a gift.  On another note, I will not be making any more purchases from this vendor.
