I bought this because I liked the way it looked and I thought well made necklaces cost way more than this so might as well buy this with EMF protection true or not (I think so but for the skeptics). I hardly wear necklaces but now I wear this everyday and I get quite a bit of compliments (when I actually leave the house __). I work half my time at home in front of 3 computers, by a printer the internet. I have a extremely pronounce chest rib cage and can feel the vibration... it's like it projecting the energy away from me.
