Our line of Black Hole Faraday Bags have been designed to aid consumers, law enforcement, and military personnel in protecting the integrity of digital information and devices. Our bags work by shielding Electromagnetic Radiation.Nothing comes in and nothing goes out when a device is placed inside one of our Black Hole Faraday Bags. This can be leveraged to protect devices from hacking, spying, tracking, tampering, and other malicious attacks. It can also be used to protect outside elements, such as personnel and other devices from the effects of signals radiating out from the device secured inside the bag. Our bags effectively shield cell phones, GPS, Bluetooth devices, laptops, RFID enabled cards, and key fobs from cellular, WiFi, Bluetooth and radio signals. Use Cases: - Device Seizure - Personal data security - Personal Wellness - Shielding from potentially harmful EM Frequencies - Science & Technology Labs, specifically device isolation - Disaster Preparedness The Black Hole Faraday Bag secures the privacy and integrity of mobile devices, key fobs and wallets. Features: - Effective electromagnetic shielding 68 dB+ shielding from low MHz to 10GHz - Wear-resistant outer canvas shell - Incorporated note slot for easy record keeping External dimensions: 8.2" tall x 7.8" wide Shielding Specifications: 68 dB+ shielding from low MHz to 10GHz

One tip though. When a cell phone has a hard time communicating with the nearest tower it will step up the power. What this means for you is that you'll want to turn the cell phone off before you put it in the bag, otherwise your battery will be drained. After eight hours or so with no use or activity I've returned to find the phone anywhere between 0 to 40 percent charged. Come to think of it, if you're picking up one of these Faraday bags it probably wouldn't hurt to pick up a cell phone charger for the car as well.
Update: I've tested this over the past few days and find that in an eight hour span there's a battery drain of only 20-25 percent.
I've tested these on cards that contain RFID chips (like employer badges & RFID cards for Arduino projects.) They scan as well as if they were in a paper bag.
Consumer, be advised: Signal-isolating containers such as these are not a "one-size-fits all frequencies" solution. The frequencies of radiation that any container like this attenuates is limited.
Know what you want to have protected and choose your solution accordingly.
A fairly expensive "RFID-blocking" wallet I bought a while back proved to be mostly useless with respect to its claims.
If you have access to a reader, be it at the store, at your work, or even at home, try it for yourself. Don't just take my word for it.
I still value this bag for its functionality with cell phones, but try not to believe that this is a bag that blocks everything in the ranges it so broadly claims to.
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.
From right next to my mini tower, I dropped my Samsung Galaxy Note-II into the bag and folded the opening over - once.
I used my wife's phone to call mine.
It went straight to voice mail!
Taking my phone out of the bag, it showed "No Signal" and took a while to re-discover the network. Back to 5 bars.
Wow. This bag is really a Black Hole for 4GLTE frequencies and all the edge network and 3G fallback frequencies as well.
