works fast
My previous heating pad was 10 or 20 years old maybe older.  This heats fast.  Instructions say not to lay on top of it - hint it feels hotter if you do... I set it in the middle wait for it to get too warm then turn it down a notch.  DO NOT SLEEP WITH THIS ON but this is great for awake people who have full sensation in their skin etc.
