I really appreciate that this exists! I have noticed when I am on my phone that my hands and fingers really start to hurt. As soon as I started to use this pendant, the pain just STOPS. Even if I'm on my phone and I forgot to wear the pendant or have it Near me - My hands start to ache. As soon as its near me, it stops. I am sensitive, so I can tell a differnce very quickly. I've been noticing when I wear it to bed, when I put one hand on the grounding sheet, and one on the pendant.. I don't remember anything else! : )
