My experience with the Pranan devices: I was suffering from headaches and insomnia, and a ringing in my ears, like tinnitus. When some cell phone towers were installed on my street, near the hospital, I noticed that I felt ill, due to the enormous exposure in that area. I felt so poorly that I thought I was suffering from heat stroke. As soon as I put on the Pranan device, I felt much better. At home, I noticed a tremendous improvement and greater stability. I no longer had headaches and I slept for more hours. Now I feel much better. It certainly works. At first, I had my doubts, but now I strongly recommend it. I wear the device wherever I go and my headaches and fatigue have disappeared, and I sleep more soundly.
