One size does not fit all
It is good in a way for stretching the neck but it feels very uncomfortable as it is too big and high for my neck, I think it is better for taller people with a long neck... When I pump it up I can barely breathe at the level where it would really stretch my neck because my jaw is in the way. Maybe if it had only 2 chambers it would be much better for me or if the chambers were smaller by design. I think for the right body build this can be very useful but caution advised it does not fit all and I do not have a short neck I am just somewhat petite and have a square jaw that seems to get in the way. I also got a soft neck collar and I prefer the smaller 2 or 2.5&#34; height so if that is your preference this device will be likely too big (high) for you.
