Gets very VERY hot!
Bought this to help with neck and shoulder tension and pain that cause migraines. Just got it frosted and have been using about an hour. I have a moderate thickness pajama shirt on underneath this pad/vest, and even on just the #1 setting(it goes up to 7), it's VERY HOT!<br /><br />Also, the neck collar is loose so not much heat contacts the neck. I clamped a travel pillow around the outside of it, which holds the collar closer to my neck, but then you need something like a towel under it because it's so hot. If nothing else, it's a great distraction from the pain.<br /><br />The velcro around the neck is very weak also.
