HF+LF Shielding Paint HSF64 5 Liter

i got a professional recommended by Safe Living Technologies who came out and measured before and after I had my rooms painted and the wifi signal strength coming into the room went from 300+(i can't remember the scientific name for the measurement of emf ) but it went down to about 2.6. I thought these were good results. plus when i go int the room, my cell phones bars go almost all the way down on service bars.

I just don't think this worked, although admittedly I did not try it with an EMR reader.
