Wacky neck is the worst....
I do not have extreme pain to start with so that's why "pain relief" is a 4. It is very easy to use and fairly comfortable. IT does what it says it does -- it relieves disc pressure when inflated.  This helps with circulation and mobility. Sitting working at a computer for hours I find that it takes its toll on my neck.  This product helps to "fix" the problem.  (I hope it lasts).
