This thing really works for me. I had major spinal surgery less than 2 weeks ago and have some fairly intense pain (similar to what people describe as sciatica) as my nerves "wake up" and start trying to work again. I was prescribed the usual drugs and was hoping to get off those pills as soon as possible. I ran across your info while searching for alternative pain treatment products. The price seemed reasonable so I have the 4x4 device a try. It took my 3 tries to find the "sweet spot," but when I did find it, I knew rather quickly that it was working. To be honest, I was very skeptical of the product. However, I was overjoyed to find out that your claims were legit. I can feel the pain return about 1 or 2 minutes after removing the device and can feel it dissipate almost immediately after I reapply it, so I know it's working. I am so happy to say that I don't need to take any more pain medication. Thank you so much for making this product available to us.
