Faraday Fabric Military Grade Fabric 98×43 inch Nickel Copper Faraday Cloth for WiFi, GPS

I’m not sure why others are complaining that the material doesn’t work, as I have tried it as well by wrapping my phone in it and messages were not able to be sent or received until I took it out of the material. If you plan on using it as a purse or something to that effect, you have to ensure that there aren’t any gaps where a signal could get out. So, for instance, you couldn’t use a zipper or anything like that to close it, and it would have to be able to be closed tightly. I simply use it to deflect signals away from my body by cutting out pieces of the material to make pocket squares or linings in my pants or hoodie pockets, and for my lap when I’m using my laptop. I also plan to make an apron out of the material so I can easily wear it over different clothing.

Works well as a ground cloth/counter poise for my whip ham radio antenna. Can tell a great difference in reception since I started using it. Very durable fabric and a great value. Will be buying again soon.

This is good stuff. I'm getting more

I have been through hell with a local tower situation. Our whole area has. One thing I have wanted was a way to tent myself out once in a while to feel better from the signals. This fabric is one good way. FABRIC COMES This looks like it is cut from a HUGE roll of fabric. That means you might get one with the sides bound nicely and only the ends ravel. Unfortunately, you might also get one with the sides that ravel. RAVELING This stuff ravels terribly. That means that you have to take care to finish the seams off perfectly. Be alerted though that this is metal so will wear down blades of a serger or a needle quickly. Also you will get a lot of tiny particles of metal threads in the air, so protect your eyes and vacuum it up right away after sewing. DOES IT WORK? This stuff WORKS. I know. I sat under it on a rough day. I could not believe the difference. I have put two pieces of this together and made it cover a queen sized bed. I put faraday tape on the center seam. I can honestly say that my body begins to relax when under this entire piece of fabric. Yeah, I tried it with devices and all of that, but honestly, I wanted it for ME. I have a 2nd piece which I sewed together and I use it for a bed cover so I can have relief sometimes. I can not use my phone or tablet underneath this either. It does work better if you gather it so I plan to gather it down on the sides and use a backing fabric to hold it in place. If you are doing to sew two pieces together, I recommend you tape the sewn area with faraday tape made for this stuff to be sure to seal all breaks in the fabric. As just the fabric with no backing, I can see through it to watch TV if desperate. LOL THE BOTTOM LINE This stuff not only blocks devices (best used in two layers or gathered) but it also provides relief for me. MY RATING FIVE STARS. This ravels so badly you have to sew it really soon to finish the edges or you will have metal threads all over the place and they are annoying. If you are going to surge this, pay attention to my cautions in this review. It is important to do so.

Great product
