Faraday Fabric 43" W×118" L(Big 3 Yards)+1.18" W×314" L Faraday Tape, Faraday Military Grade Conductive Material

Good quality and less expensive than other offerings on line .

I tested this fabric with a variety of radio devices and it definitely works. Even in frequency bands below the rated 10 MHz minimum range, it still substantially attenuates radio-frequency (RF) signals.The fabric is somewhat delicate, as noted in the listing. It's basically a fine mesh made from polyester fibers that have been coated with extraordinarily thin layers of copper and nickel to form something that shields like metal foil but remains soft, flexible, and non-crinkly like cloth. It corrodes when exposed to water, especially in the sun. I exposed it to skin oil and didn't see any obvious corrosion after a week, but I'd still be careful about that.The real question is, what do you need it for? The included "home DIY production manual" has some ludicrous ideas in it, like using the fabric to wrap your Wi-Fi router. Do not do this! If you're using only the Ethernet ports on your router, just turn off the Wi-Fi. If you aren't using it at all, just unplug it. Leaving the Wi-Fi on and wrapping this stuff around the antennas is a waste of electricity at best, and could possibly damage the router.An even nuttier suggestion shown in the manual is to drape the fabric over the belly of a pregnant woman. I don't want to harsh the company's vibe, but under ordinary circumstances there's no benefit to this. The kind of RF signals to which we're all exposed in our daily lives pose no danger whatsoever. If you happen across a pregnant woman in an area of extremely high RF field strength, on the other hand, you need to remove the entire woman from the area immediately rather than just shielding a portion of her.Most of the manual shows how to make a pouch out of the fabric to hold devices in situations where you don't want them to operate, and sometimes this makes good sense, like shielding highway toll tags when you're not using them. This fabric can be used on its own, or used to line some existing carrier like a wallet or purse.But there are many, many products on Amazon that consist of this same sort of fabric already sewn into a more durable cloth pouch, and not very many people are ever going to need to make a full-custom RF shield for something that won't fit into one of these pouches. If you are one of those people, this product will probably work for you, and for that reason I think it deserves five stars. But you're probably not one of those people, so you should probably not buy it.

Too stiff for small sleeves. Excellent for walls and large boxes

This kit is perfect for creating a faraday cage in your office or car and there was plenty enough to line a cabinet.I have a wood cabinet that I wanted to store my electronics when not in use. Honestly if I had the money I would order multiples of this item and just hang it like wallpaper, window shades, ceiling cover and floor cover and even make a curtain to go across my door with it. But I can't do that right now so I ordered this kit and it was perfect. My cabinet is 24" wide by 24" deep by 36 inches high on the inside. So I lined the cabinet with this material using the included tape and some duck tape I already had being careful to overlap the seems. I got the entire cabinet lined including the door and everything I own that is electronic except my TV and a couple of cheap radios fit inside protected from electromagnetic pulses or any other stray rays.This material cuts like satin and is very easy to work with. It is light weight and thin so you could use it to make little Faraday pouches to fit in your shirt pocket. In fact I think you could line your shirt pocket with this material and not many people would notice the extra layer of fabric. This is truly a wonderful invention.I highly recommend this product to protect your devices and your privacy and your banking.

I wrapped this fabric around my WiFi in hopes that at night when not in use it would stop or at least greatly reduce the signal strength coming from it through my sleeping bod. Unfortunately, altho' wrapped tight like it was in a cocoon using several layers, the signal was excellent all through the house. I might as well have wrapped toilet paper around it. In fact, the signal actually seemed stronger than ever after i wrapped it in this material. :(

This works great. I keep the loose fabric in my shoulder bag (Man Purse... lol) or my backpack so that I can easily pull it up and completely wrap up my electronics quickly and efficiently on the go. My next project is the line a lock box that I use for transport, but I haven't done that yet.When my electronics are completely wrapped up in this faraday fabric, NO SIGNAL at all gets in or out of it. I even laid my phone side by side together. One in the fabric, the other just open. I couldn't get either of them to get a signal from the other. The wrapped one could not get any signal at all and was completely unaffected by my buddies EMP generator.This will absolutely, 100% work with phones and electronics if they are COMPLETELY encapsulated with this fabric.

I've read about building Faraday cages before, but until trying it myself with this material, I was surprised how a super-tiny gaps in the seems between fabric pieces let significant WiFi bandwidth leak in or out. Which means: the velcro dots provided by the vendor are useless...I think you'll need double-layer seems that are each tightly stitched.The vendor provides a huge fold-out page with various DIY suggestions for covering objects. But their designs are all doomed to fail, in my opinion, without a separate layer of welting of their own material.For inserting whatever you want to protect, I doubt a simple fold-over flap is sufficient (e.g. pocket flap on a shirt or jacket). You'll need a flap over the flap, and then some way to scrunch it up tight.But all that said, the mesh size of this fabric works amazingly well - even a single layer: I could see through the fabric to my iPhone screen inside. When I crammed down multiple layers of fabric bunched around the perimeter, the signal dropped to zero. But the slightest let-up on squeezing the fabric around the back / sides, and the signal strength bounced way high.
