Works but..
First the item works after you figure out how to put it together (really not difficult but a few question areas) since the directions are not very good.  Advertises with what looks like a cloth carry bag which did not come with the set. It shipped in a zip lock type bag. If that's the travel bag then it is really a joke.  The velcro strips on the chin harness are extremely short & made for a smaller head/face.  I had to buy additional velcro to make sure it attaches properly. After all of that & finally getting to use the device I have to say it provided relief to my pinched nerve in my neck.
