HoMedics (Model NMS-350) Neck Massager Shiatsu and Vibration With Heat.
This item was previously owned and used. The cord is really long, which is a nice feature. Plugged it in long enough to ensure heat worked, and it does.
Did not try on my neck or head, but I did put it on my knee. It felt good not too much of the hard kneading like some.
