Belifu Tens Unit
Didn't even know there was such a thing until my daughter introduced me to this.  Stay so tense and have muscle aches in my shoulders and neck.  It is so bad I can't get my head in a comfortable position to sleep at night.  Decided to purchase and what a difference...It's like going to a massage parlor.  I love it.  Would highly recommend this unit to anyone out there with muscle aches...don't think you would regret it for a minute.  Money was well spent and worth every cent.
