Q-Link
I bought mine several years ago and lost it.  Noticed the change within a few days.  Headaches, specifically.  Could not replace right away, so resorted to amber crystal wrapped in copper, and prayer until I do.  I never took off except a couple of times within 4 or 5 years.  It feel off when string broke.  I had used sterling silver chain, but it was getting too hot to wear in a sauna, so switched back to non-leather cord. Want to compare it wth the one that protects withn 45 foot radius. I placed a mini-Qlink on my cell phone meanwhile, but it is not enough to block EMFs form all my appliances, wheelchair battery pack, computers, TVs, train stations, airplanes, and buildings where a lot of electrical power is used.  The SRT-3 pendant also stopped the electric shocks I used to get from static electricity.  The technology works.
