great design
I have neck pain and this guy is great for it.  I had a normal shaped heating pad and it was a pain for bunch it up to hit my neck right.  The cover is super fluffy and comfortable.  It only has three settings though.  My other one had 6.  the lowest one isn't very hot at all so if you need it to get really hot, this might not work for you.  But if you just want it for sore muscles, the shape is great and it gets warm enough to do the trick.
