Earth Grounding Faraday RFID Shielding Fabric-Block WiFi/RF-Anti-Radiation Conductive Magnetic Copper/Nickel EMF Protection Fabric Width 43" inch/Length 39" inch CU-NI-DIMD-1PIECE

I put my cellphone in a metal sauce pan with the matching perfect fit metal lid on top (lid has lip which goes into the pan itself, no gaps) and the phone still rang when my wife dialed my number......but this stuff? I wrapped the phone in it, rolled it up actually so it had 3 layers on each side, and phone would not ring......so I'm assuming (one) layer offers (some) protection, no doubt. You can sew this into the lining of a coat (use it (as) the lining).You can drape it over windows. Line the back of your bed's head board with it (wires in your wall are right near your head when you sleep)..You can fold a square up to line your wallet and protect your credit cards (and dollar bills) from remote readers...You can even line the inside of a hat with it (3 layers too) and say good bye to the tin foil...In fact, write a message intended to make no sense at all, and using words from 6 different languages, wrap the message in the old tin foil, then fold it into a hat shape, and mail it off to spook central in Langly VA.

Our house lights are RF controlled and when you click on a color, ALL lights would receive the signal and sync up. With this fabric, I was able to wrap each lights (including remote) and change colors individually!Only one layer was needed for what I needed done. Thank you!

I really didn’t think this would work but IT WORKS! I put my iPhone in between the sheet and it went from 4 bars to 1 bar. The reason why it was at 1 bar was because I was peeking to see if it went down. I’m sure 100% if it was fully covered my iphone wouldn’t work! Thank you so much and for the price it’s worth it!

The description should begin with the fact that the fabric needs to be doubled or tripled to be truly effective.

I like that you can use this in many different applications, either if its trying to produce quiet time for the family, or if you just want to break from technology more specifically radio waves.
