Amradield Faraday Fabric 78"x 43" Faraday Cloth Tape Nickel Copper Polyester Material Influence RF Signals WiFi Cell Bluetooth RFID Guards You Against Harmful Frequencies and Possible Data Theft

This isn't a bogus review. I tried several shielding cloths that resulted in disappointment. Order this cloth because the roll length and width would be perfect for my use case. It took a while for delivery because it seemed to ship from overseas but the tests conducted blew my mind. with minimal wrap of layers over 4G and 5G cell phones and AM/FM radios it actually blocked signal completely. I had to retest this several times in different locations to make sure its blocking performance was a fluke but it did block regardless of location. Seems to good to be true but the cloth I received works the best of all I have tried so far. Even better than heavy duty 27micron aluminum foil I tested which I don't understand but is true.

Made credit card, packset, GPS, iphone and emergency radios covers. After testing the material I discovered one layer wasn’t enough to prevent electronic signals from getting through to the packset and iphone so I doubled the material which did the trick!

This fabric reduces rfs nicely. In fact, I made a cover for my cell phone, and with the flap closed (effectively making a faraday cage) the phone will not receive any calls. Since this defeats the purpose, I leave the flap open and rfs are reduced by at least 50% imo. Sometimes it's more, so 50% is an average - it's hard to measure exactly because a cell phone pulses rfs in intervals and the pulses vary in strength. As for the router and Arlo, which boom rfs that peg the meter, the fabric also works. Ror the router I had to make a nearly complete faraday cage to get the rfs down, and just draped some fabric over the Arlo base station. Now my hobby room is not being blasted so much. The fabric is easy to cut and sew. No issues. Great price.Don't know why some reviewers say this doesn't work.

Good stuff

Wrapped my cell phone up in one layer and laid a stapler over the open edge, called my phone from another and it would not ring - went right to voicemail. THAT is what I wanted out of this fabric. I am inserting it into wallets I make to inhibit credit card skimming so this is the perfect fabric for my needs. It's not flimsy, so it's easier to cut and sew with than other fabrics I have purchased.

Did the trick

Got this to put on bedroom wall that my electrical panel is on the other side of. Did absolutely nothing. Same reading with or without. Super disappointing.

I bought another RFID material besides this one and they are both great. If you read another review of mine and notice I bought two different RFID fabrics, no worries, I just needed more at a fast rate! This fabric is a must for handbag makers, wallet, coin purses,...It is a fact in today's world we have to protect information and this fabric does the job!
