I would just like to thank you and your company for this miracle invention. I have suffered from excruciating headaches almost my entire life and have basically become dependent on aspirin which is terrible for my stomach. My boyfriend also has a very painful upper back injury. Needless to say my boyfriend and I quickly began to fight over the device once we experienced the effects. So i had to come back and order one for me (i got the bigger one this time!) Also a side note: I don't know if this is typical of your results but i had burned my hand very badly (2nd degree burn with blister) and because the pain was too much to bear...
