About a year ago my energy level was very low, and I was often fatigued. After doing a bit of research I decided to try a scalar pendant. I ordered the Quantum Science one from amazon. It is really discounted there. When I put it on, I could feel my energy field being infused with a different kind of energy. The energy builds up around the body for a couple of days. But, if I am without for more than 2-3 days, I can't get through the day because of fatigue. I just got one for my mom, who was feeling lightheaded often in the recent months. After a few days wearing it, she stabilized. Just our experience...
