A Little Scary
This thing functions as advertised.  You put it on your neck, pump up the hand air pump to fill it with air, and it stretches out your neck and raises your head.  It feels good, but a little weird.  My wife and I kept worrying that we were going to injure ourselves, break our neck, cause paralysis, or something like that.  We never really pumped it too much, but it did stretch our neck and it did help with neck pain.  My son used it too, but he hasn't given me any feedback yet.
