Broke in a month just cheap string and the  beads are mostly gone no chance of repair, the return window closed on the 9th this is the 17th so I got burnt again by cheap made in china junk. I was under the impression this thing was loaded with magnets. If my neck had better history maybe I wouldn't need more than TWO! Yes TWO magnets that is what you get with this ripoff! I am gonna trash it and look for a better one because it supplies absolutely no relief from chronic neck pain the piece of JUNK!
