EMF Protection Plug In Device

I love this & I can tell it works if you're in the vicinity of the room. I don't know if you need one for every room or not but I'm gonna buy another the 6 next month for my plug that my router is plugged into. This first one I have in the living room, plugged into where the TV is bc that's where the majority of my "technology or devices" are being used. I love this company. I made my first order for the ormus gold & pine pollen & another product & this shipping lost & after 2 weeks, I emailed them & told them the problem. They sent out another order that was here in less than a week, at no charge. The other lost order came after 3 &1/2 weeks. I don't know what happened but they corrected it & made it right. I was blessed in the process!
