Neck issues, buy this collar.
I have had neck issues for some time now.  I have tried other cervical collars, but this one is the best one I've ever tried.  The interchangeable pads allow for me to get ultimate support while sleeping and the heating pad provides tons of warm comfort while relaxing in my chair.  If you have neck issues, just buy this collar.  You'll see why I say that.
