We have been into alternative health and herbs for years. A long time ago we began studying the effects of EMF’s on the body. Naturally we found and bought a couple of EMF readers….So we try each day to ground out on concrete but it can be inconvenient. We knew something like this grounding sheet tech existed but who to trust? So many scams out there. Long story short we came across this company from a friend who has recommended several health items in the past which were all A+….So we took a chance. Mind you my wife and daughter are extremely emf sensitive. We can be driving and my wife will be like ouch my leg is hurting and I will look around and sure enough hidden next to a tree is a 5g tower, she had no idea. THESE DOWN TO GROUND PRODUCTS ARE AMAZING! They work! We all feel wayyyy better. A few minutes touching this product feels about the same as 30 minutes grounding on proper concrete or grass! We normally keep our cell phones on airplane mode as much as reasonable and our router unplugged. Ofcourse sometimes u have to have the EMF’s turned on. With these products you turn the EMF’s on and when we touch the grounding sheets, pillow etc it’s as if u have no pain, the EMF’s flow right through and out. We have used these products now at several hotels….haha EMF’s no more! Walk into the hotel room, doesn’t feel great, plug these products in and ahhhh rest! Truly great products !
