The heating pad is easy to handle. Just put it around her shoulders, best directly to the skin, the reference is luxuriously soft. Then adjust the heat (I always take as warm as it goes) and close by magnet. Now sit back and enjoy. I could hold out for hours (I do too!). Very soothing for tension and, as I could see now, with colds. I have a heat pad just upside dressed (a little wick on the chest) and then the painful areas were already warmed. As you fall asleep, despite cold one instantly.
Addendum 01.2014! The heating pad is still all the rage! I have already washed several times, because you can "cut the cord" cable yes. Should it go wrong now, it was worth more than his money and I buy a new IMMEDIATELY!
