This is a great way to get the weight of your head off of your neck without hurting your jaw (like the water bag over the door thing).  You can release if your jaw gets tired and then take it up again.  To begin I take the bulb off and blow it up by mouth and then put the bulb back on and fine tune it.  Easy to travel with too!
