Easy@Home Wireless Rechargeable EMS and TENS Unit

URRRGGG The amount of frustration I have for this product is maybe a little more than I should have. Okay so I charged this baby up for the 6 hours I was supposed to. Done! I put it on my back- pressed power and then I tried to press the up button to make it so that the intensity would go up-I was really hurting here! Then nothing. I was like okay maybe I pressed the wrong button. I put it on my leg and tried for round two. You will never guess what happened again. Thats right. Nothing. I asked two other people to try it and still nothing. So frustrated but I will keep trying.
