Neck Traction
I like the old style (water bag) better for a "permanent" location, though I did get tired of the bag springing leaks, which is why I thought I would try this style.  This would definitely be the best if you needed to take one with you, but it is clumsy to use.  This particular brand is more comfortable on my chin, but the velcro seems to be positioned for a neck size smaller than my 16, so it's a little too snug there for my taste.
