No more headaches!
I installed this right in front of me at work. I have 3 monitors, a laptop, 2 cell phones and a desk phone in front of me.  I have experienced headaches on and off for a while now.  Once I learned about dirty electricity and EMF's, it started to make sense.  I received 4 of these, 3 are in my bedroom, and one in my office just in front of me, and I haven't had a single headache.
