At first, I didn't know how to use it, but after looking at the detailed page and trying it out, it felt exactly like the physical therapy I received. The 3rd level seems quite intense, so I think I'll have to start slowly from the 1st level.
I bought this because I had severe shoulder pain. When I apply it, I can clearly feel the electricity flowing through it. Even at level 1, it's quite strong, and it was painful when I accidentally touched the inside. When I apply it to my shoulder, the vibration is strong enough to feel like someone is tapping my shoulder, and my body shakes as if I'm having a mild spasm. Once applied, the adhesive loses its stickiness.
Excellent product, works perfectly, came well packaged and arrived on time. Buy without fear, it helps a lot and really relieves local pain... I recommend it.
After using it a couple of times on my lower back it looks i feel less pain and getting up from a chair with less effort.
The remote control doesn't have added value for me; you have to point it to the unit, but the unit is on my back, so i don't see the buttons.
I did see some reviews complaining about getting a shock; you have to apply the patch on your body first, before switching the unit on and also don't remove the patch from your body while the unit is still pulsing!!!! !
It's good to use considering the price.
