I who often migraines with severe pain to the neck I wanted to test this without being convinced (see comments saying it does not warm enough). Upon first use I was conquered, very well heated, I put over a thin sweater and my neck was burning desire, you need to relieve ... Migraine soaring! Indeed on the lowest heat programs is not intense but more like a "cocoon" that prevents the cold, for a "healing" effect change rather strong programs. I recommend it!
