I have had my daughter on the phone and wrap it up and after about 15 seconds the call is dropped. I can hear her but she cannot hear me. I have a sheet wrapped around my tablet and laptop inside the laptop bag. The extra one I haven't used yet.So far seems pretty worth having. And versatile and super easy to use because I don't have to have a bulk bag and try to put it in my laptops case or have a useless case, i can literally wrap it and slide it in and be golden. The quality looks and feels good and functional wise you can use it in a multiple of ways that i can think of! The sheets are a decent size and you couldn't ask for an easier product to use. Just wrap and go, that simple. If you want you can use the tape it comes with also.

The title says it all. I was using a magic carpet a (metal window screen) in which to serve as groundham radio antenna. At least for the difference has been difference between night and day. Another plusfor me that it is not as bulky and can easily be stored. Indoors I want use any radials.

New info, I tried this versus my Yubikey and a single layer of this stuff is sufficient to make it unreadable. For my purposes I'm gonna call this good enough. If it's killing NFC to the Yubikey then the wireless cards in my wallet should be decently protected.--- original review ---I pulled it out of the bag, tossed my phone into the pouch of folder over material and called it from another phone. It immediately rang. I tried from my smartwatch and Bluetooth was unaffected and I could even stream video off of it. I then turned on a wifi strength grapher on my phone and chucked it back into the material.Two layers are good for 12-15 dB of attenuation at 5.8 GHz WiFi, that's it. I tried it versus an single layer of aluminum foil and it's better, but not as good as a single layer plus my hand.Is this product completely worthless? I'd say no, but it's far, far below the nearly 100 dB attention they claim. It's not crinkly sounding like straight aluminum foil is, so I might wind up lining my wallet with it to help shield my cards and Tesla key, but it's by no means the portable dead zone it claims to be. I'm definitely considering returning it.

Radio communication was broken as soon as devices were wrapped in the material, so it works in that regard. I purchased this to test some theories of mine regarding differences in audio rendering performance in the software domain, and possible issues with error correction or rather lack thereof in my DAC (which otherwise measures excellently as far as the usual tests go) which don't result in failure but reduced audio fidelity due to inaccurate or missing information. I'm thinking interference is an issue, and at various price points a certain amount of effort is put in to combat the issue, which isn't really a huge problem when people are otherwise fine with the not so perfect sound quality, it's more than good enough for MOST. So I figured that I'd go after anything that I could affect in regards to minimizing "soft" errors. Bottom line is that after getting a more responsive linux kernel installed to get the most out of the software, networking vlans and priorities, clean power supplies and galvanic ethernet isolators, placing all the switching components in a faraday cage, I heard more music and finer details, more specific spatial cues, etc etc, more basically. I use a modded Topping DX7 Pro and I placed it within the folded material and my wife and I immediately noticed even more detail. Prior to placing the DAC within the folds of faraday material we already were hearing that realism we've been chasing and thought it was as clean as we could get with the equipment in play. It gets better. I don't think this in the analog domain, I think this has more to do with the DAC potentially utilizing more bits of precision, or it's limit (I read that it's 20bit effective after conversion to analog) is more consistent with less radio interference present. Whatever the case, noise rejection is important for audio, $26 of fabric improved my audio in a way that would have required a component upgrade. And if you just want to block cell phone signals, it works for that too. lol

The media could not be loaded. I am completely blown away by this product kit. Please watch my video to see the faraday bag I made. It is better than all of my other ones combined. Including the silent pocket 10 liter dry bag! I wanted to create a bag that Is for SURE going to protect against emp. Apparently mission darkness is very conservative with their recommendations because the 2 layer bag I made with this kit, (that perfectly encloses the bag the kit came in) blocked 8 watts of gmrs transmitting from 1 foot away. They tell you in the directions that to block a two way radio, you need at least 3 layers and to be 30ft away. If you make a bag properly with the correct folds and use 2 layers. This material will stop anything in true faraday cage fashion. Btw. Wifi. Cell signals, etc will be stopped likely with 1 layer. That stuff is easy and all my other commercial bought pre-made bags can do it. But not one of them can stop 2 way radio. This thing does it and then laughs in your face. The magnetic/electric field gets so wacky, that when you hold the transmitter like 6 inches from the bag or closer, the receiver blurts out this demonic like electrical wave. It's just the magnetic fields competing and it's really weird. This product is the real real. Thank you mission darkness! Will be buying much more.
