Faraday Fabric 43" W×118" L(Big 3 Yards) Faraday Military Grade Conductive Material

I use this fabric, along with foil tape, to make EMP safe bags to put electronics in just in case of an emp. I like that the fabric comes in huge sheets that allows you to cut to fit whatever you plan on putting inside the bag. I have tested the bags that I make with this fabric with cell phones, am/fm radios, laptops, and HAM/GMRS radios, and they block the signal from all of these devices. The fabric works as described. Great alternative to bulky metal boxes and cans.

I am on the 3rd floor of my apartment and my body appears to be in tune with the cell phone frequency & what ever else is floating out there. I put the Faraday over my bedroom sliding glass door. I am sleeping so much better. I am not waking up as much though out the night in pain. So this product is blocking something. I could not recommend it enough. You can cut it also for phone and such. My Daughter in law is expecting a baby-you can also cut a square to put over your baby bump to protect your unborn child from rays put off from laptops!!! I am a believer after a week of use in my bedroom. I bought 2 more already. What a valuable item with versatility for use with electronics!!Good Luck!!

A really nice sheet of EMP shielding. It is big enough to wrap around a number of items I want to protect. Very flexible and and conform to many shapes and sizes. That said I tested it. I wrapped a thing layer around my cell phone and called it. It didn't ring. I tested the find my phone app on my Apple Watch still no beeping. I conclude from this that this is an effective shield. I hope to never have to prove that it works for and EMP.

Aside from the completely laughable advertising copy, this material has a few good uses. 1) Small bits of it can be used to repair worn-out conductive rubber pads in remote controls. 2) It is conductive on both sides and measures very low resistance with an ohmmeter. 3) I bought this for a ham-radio "magic carpet" portable antenna grounding scheme. I added some tarp rivets in the corners for hold-downs. This package version also comes with some rather useful sticky Velcro pads.Want a good laugh? Read the advertisement.1- Wrap your monitor up with it to reduce EMI....... so you can't see the screen????2- Wrap your cell phone to reduce radiated RF into your head....... so the phone's antenna stops working and drops the call???3- Wrap up your WiFi router....... to reduce it's range?????4- Wrap up your laptop for EMP protection...... who's Internet provider is going to work after the big bang????5- Wrap up your desktop computer....... so it overheats and fries?????6- Wrap up your Echo...... yep it may disconnect, but it won't mute its microphone, if you care.7- OK you can make a decorative curtain out of it. Its nice and shiny. But there's cheaper alternatives.The only one that makes any sense is a wallet wrapper. This might actually prevent card probing.

Doesn’t work at all. Read signal strength and it didn’t affect at all . Too late to return .Wrapped a Bluetooth keyboard 10 feet away from it’s toggle and had full strength as well as my phone.

The media could not be loaded. I wasn't sure about this fabric, but it works. It's best if it's a double layer. When I opened the package it seemed almost paper like, it's sort of like a thin taffeta. I didn't have a needle and thread on hand, but made a little phone sleeve with the tape and velcro that came in the package. When in the pouch my phone has no wifi and no cell signal. However the alarm still works. I put my phone on airplane at night, but this is just an additional step to mitigate these frequencies when I'm sleeping.There's a new build 3 unit condo across from my bedroom with smart meters facing me. I'm thinking of buying more of this fabric to attach to my bedroom curtains. In this increasingly toxic world it's important to protect yourself. I'm going to buy a small sewing machine and attempt to make some ponchos put of this. Hey I might look crazy, but if it helps on my commute passing all those 5G towers then I'm all for it. I'm also going to line my fanny pack with this and line the pocket of my purse where I keep my phone. If it's not doubled you'll still get the signal, but it will mitigate the effect that the phone has to the body.

When I got the fabric, I tested it out by wrapping my cell phone in it then trying to call my cell with the home phone. It blocked the signal perfectly! I also tested it against a four layer wrap of aluminum foil and both methods worked well to block the signal and keep my devices safe as promised. It is now keeping my devices safe. A good product, especially if you make a cell phone or laptop case out of it. It is easily carried and easier to remove your devices when you need them.

Sews well and the glue on the velcro tabs is very sticky. As for how well it protects, we'll have to wait for a nuclear bomb to find out...
