Doesn't come complete with the charging mechanism which is needed to function.  What?
I got this for neck pain.  I got the first one, thought the charging mechanism was missing.  I said so, sent it back.  Another came without the box.  So, I read that other people felt as duped as I did.  Very brad product.  Don't bother or you'll have to invest money in making it work.
