I can't say one way or the other if these work, but if you want a personal EMF protector here's the site with Don Croft: http://www.worldwithoutparasites.com
BioPro Q link pendant is also said to work.
Doc told me he uses a crystal. He can tell you more about it.
I'm not sure if it's related to our question or not. I'm not really sure if this balance bracelet you talk about is related to EMF protection. My response may be off track, but I've tried, anyway. This info may be of interest to you.
This bracelet is supposed to balance the body's ions. It's effectiveness has been challenged. It sounds like a hoax to me, but maybe it's not.
