Thing totally works. Just remember if you have a case on your phone to protect from dropping, scratching etc. You might need a bigger size than ya think. This one is a tight fit for my Galaxy in it's shock resistant case, but it really works so I'll be buying the next size up so it also fits credit/debit cards and car fob...I think the tablet sized one is probably perfect.

Terrific product, important to own this item if security is a concern. Quality materials, well stitched made in America. My large cell phone fits inside with room to spare. Your device is completely invisible once inside, all signals are blocked, huge piece of mind ! A+++.

I looked at dozens of Faraday bags on Amazon before selecting this one, based pretty much entirely on the reviews. I was a bit apprehensive since this one is considerably more expensive than most. At the end of the day, it's a sheet of metal fabric wrapped in cloth.This bag exists for only one purpose: to block cellular RF signals from whatever's inside. Either it works as promised or it doesn't. As such, I tested it by dropping my phone in the bag, folding the top over twice as directed, and immediately calling it from another phone.The verdict? It worked. My phone could not be found by the cellular network and the call went to voicemail.A couple things to note:1. The density and composition of the mesh fabric determines the range of radio frequencies that are blocked. I'm satisfied that the bag does indeed block common cell frequencies, and others have claimed that it also blocks the frequencies of wireless car key fobs. Beyond these, I wouldn't expect this bag to block devices like AM/FM radios, ham radios, walkie-talkies or the like.It may block Wi-Fi and/or Bluetooth; I haven't yet tested this.2. Many people (including manufacturers) claim these bags also block GPS signals. Whether they do or not isn't really relevant since GPS signals are one-way: they fall from the GPS satellites onto your device, which computes your position based on the strength of signals received from multiple satellites.GPS-enabled devices do not transmit anything back to the satellites (in fact the satellites are not equipped to receive anything from customer devices -- they are one-way, transmit-only devices).If you're concerned about your device betraying your location, blocking the cellular signals is what you want. Once your device has computed its location via the GPS radio, that data can only be sent back to interested parties (such as apps, for example) via the cellular network, Wi-Fi, or in some cases a connected bluetooth device. If your device cannot be found on a cellular network or Wi-Fi network, your GPS-computed location cannot be leaked.The bag itself appears to be well made. The outer fabric and stitching looks strong. Not sure what the point is of the clear plastic pouches -- anything in these pouches will most certainly not be protected. Also, the "fold top over twice" business is messy and results in a sloppy looking bag. A better mechanism, even snaps or a buckle, would look better and be more secure. The bag's natural tendency is to unroll itself when fastened with the hook-and-loop mechanism. This tendency probably isn't strong enough to completely unroll, but it could have been avoided with a better fastening scheme.
