Being an engineer by trade, I wanted to know it worked. Personal testing has shown the Aulterra Neutralizer and Energy Pillows to be effective.I know now that me and my family members (having put one on each phone and computer) are safer because we're using the stickers with the Aulterra product impregnated into it.The Energy Pillows have shown to be effective in speeding the healing of some common ailments. I also sleep better as well with an Energy Pillow under my pillow.
