The point of this one is that nobody can tell you are wearing it. It sits under your clothes around the waist, and gives you steady warmth plus a low vibration on the lower abdomen and back. Three heat levels and several massage modes, so you can turn it down at your desk and up on the sofa. Cordless and rechargeable, so you are not tied to a plug socket or reheating a wheat bag every hour. HOW TO USE IT Fasten it around the waist over a thin layer, not directly on bare skin. Start on the lowest heat. It times out on its own so you cannot fall asleep with it running hot. IN THE BOX Heat belt and USB charging cable. DELIVERY Typically with you within 9 days. 14 days to change your mind.
