Works for me!
Interesting device.  It took a moment to get it in order, and situated around the neck, then you just pump it up with the pump, which is just a manual blood pressure bulb.  You tighten and loosen the small metal knob near the bulb to release the pressure.  Honestly I don't know what the blue clip is for - the metal knob held the air in perfectly.<br /><br />The neck cushion is made of a soft velour, and is totally comfortable.  All the metal grommets are secure and well made.  The two Velcros, top and bottom, could have had more of the one attached to the cushion.<br />Overall, I've found this real useful for me!  It feels like my head is floating and it's wonderful!
