Absolutely Perfect & now I am sure it works!
I received it about 2 weeks ago. And I decided to test it out with my own equipment and the app. The results are absolutely amazing. I want to put this on my body and wrap other things for emergency. I get radio frequency exposure everyday and wifi and what not at work. I work near a cell tower. Like it's near me, less than a 80 ft. I think I get bombarded everyday. With stress and all the electronic IT stuff I do I have a weird pain all over my body, rheumatoid arthritis, allergies I never had before, asthma that I never had, IBS, fibromyalgea, etc. This all occurred when I took this IT job. It is really bad and I am quite healthy and eat right too. All of a sudden from a go getter I am getting more crippled by things health wise. One day I read all the legal stuff about cell and wifi research and noticed how careful these legal notices were in trying to get users to put the devices away from the body where before studies were inconclusive. My migraines were getting bad. Yes I am already eating a diet to address leaky gut and have been for years yet it has done nothing. I have been using this for about 10 days and I feel like I dont have much pain, all the tiredness start fading away. I have also covered my wifi router with this faraday fabric and guess what? I couldnt connect to internet :)

My subjective test shows that it works...
I mounted a WiFi Access Point at a location that was measurably the best overall location to cover my home. When I realized the access point was directly under my bed on the floor above, I began to wonder if the relatively near-field, long-term exposure might be dangerous. In any case, I found this conductive fabric and decided to give it a try. Pictured is the result of my subjective study of the fabric, which involved examining the strength of the signal that my phone would receive with and without the conductive fabric in the way. ... I gave the fabric 4 stars because it does measurably reduce the signal strength of that articular access point, although I think I was hoping for a little more reduction. I am not qualified to suggest what would be "good enough" reduction. It did not reduce network signals not in-line with the fabric, as I would expect. Interestingly using two layers of the fabric did not seem to reduce the signal any further. Also placing the phone near the edge of the fabric did not appear to reduce the signal either. The fabric is very thin but seems durable nonetheless.

Simply doesn't work
I have a spot on my wall, behind which the main power to the house is run. EMF is very high about 12" out from the wall. Bought this to see if I could reduce the EMF. It did nothing.

If placed over a cell phone - phone will not receive any signals. It works! :)
I was impressed by the 5 star reviews and decided to take a chance on buying it. The sheet is very thin and is a beautiful low lustre gold colour. Though it is supple enough, you can feel the metal fibres in the fine weave of the textile. I have had this piece hanging on the side of the bed blocking the neighbours WIFI next door. Today I did a test and put my husbands cell phone on the floor under the sheet ,and called the number. The call went straight to voicemail. I took the mat off and dialed again and the phone rang. I did this test 2 more times just to be sure. So happy it really works. My only worry is that if you have it to block radiation from one (directional) source, you really need to have them all around you to completely block out the other waves. For example. we have 3 cell phone towers close to us - I imagine they are hitting the sheet on one side and the waves are being reflected or bounced off it - onto us sleeping, thereby maximising the radiation. I suppose the EMF blocking curtains would work better for a bed area. a tent shape would work best for the bed area. This is a great 'blanket' for flying and as advertised, to protect babies. I enclose a photo to show its size. Great customer service: I wrote to the manufacturer's asking how much of the EMF radiation is blocked by the sheet. They replied the same day. Hello A. Eastman Thanks for your Question. WiFi fields NEED a protection from 40db.That's a minimum. It's necessary to ensure protection. The Nasafes emf fabric have a shielding effectiveness of 55 - 75 db and can protect to 99%. But, you need to know, WiFi routers scatter the radiation. The farther you are away from the router, the greater must be the shielding area. See on image attached. Building materials and their protective properties WiFi - shielding effectiveness in % Brick Wall 18 cm = 40% Reinforced Concrete 16cm = 90% Solid Wood 16 cm = 80% Nasafes mat with copper/nickel mesh = 99% (Provided that a large area is covered) A grounding is required! If you cover the wall to your neighbor, than please create a connection between the floor and the emf fabric mats. For example, with a simple cable, or the mats themselves.(Simply clipped or glued to the floor) Please let us know if we can enhance our service to you in any way. Thank you, Nasafes

Absolutely Great Quality and works perfect.
First of all: Great Packaging! I've put my mobile under a couple of folds and tried calling it and it was not reachable so it definitely works. I like the size as well. I have tested the same with our WIFI Router and I was not able to see the router on my WIFI list, so this product is absolutely great. I did buy the similar ones from other companies before but the quality and function was not that good so I decided to go with Nasafes. As it works very well, I highly recommend this product. This Faraday Fabric is pretty easy to work, blocks wifi if that's what you are looking for. I have tested with different products.

I bought two of these to hang on my wall ...
I bought two of these to hang on my wall, which was next to my outside meters. They did not do a thing to stop the EMF. Will try something else. Am changing my review of this product, since I found out I had to ground the shields. Will do another review, after I try doing it the proper way.

Similar to the material the RCMP and CDN military use to protect themselves from their own "non lethal" weapons. An extra layer of protection from the neigbour's WiFi as I sleep, better value than some other products too. I can't wait until people wake up to this invisible danger which is ruining many people's quality of life and health. Brilliant idea to package and market this product for the masses. My cell phone using niece discovered she was sensitive to Electro-Smog recently while driving her Prius and found this product in an effort to deflect the EM radiation from the electrics around the console and dash area. She'd get sore shoulders while in the front seats only. Great product, easy to use and can be adapted to several different applications.

I use this under a 100% cotton bedsheet. To connect it to earth I lay it over an earthing mat. Although the earthing mat would probably be sufficient on its own, I wanted a larger area and its definitely made a difference. The first night I had lots of vivid dreams but that settled down and now I have the most amazing deep sleep. It does need hemming at the edges to stop it fraying. I washed it by hand and it dried by itself within an hour or so. Much better value than the fitted sheets. Fantastic.

No se si protege de la radiacion o no pero la compre hace como dos años he hecho bolsitas para el mobil y la cartera..y por lo menos protegidos quedan...debe ser muy buena porque siempre esta dentro del bolso manoseada. y la he lavado..y sigue igual, más o menos
