overpriced heating pad
I am a physical therapist and have to say that I don't see that this very expensive heating device is any better than a heating pad.  IN addition you must stay tethered to the wall outlet you are plugged into for 15-20 minutes at a time.  Do you honestly have time for this every day?  Keep in mind too, that this is being sent from Canada (I love Canada!) so if you want to send it back you have to pay a lot to do so.
