A very good portable heating pad !!!
I was looking for a portable heating pad for my back pain and found this one. The unit comes with a rechargeable battery and it is very easy to use. There are three temperature setting (high, medium, low). It heats up very fast and I can even feel the heat when I wear it on top of my jacket. The pad has 6 vibration mode with different massage intensity also.  It is very comfortable to use hot compress and massage at the same time. After several days use, I can say I am very happy with the purchase and highly recommend it.
