Mission Darkness Non-Window Faraday Bag for Tablets // Device Shielding for Law Enforcement & Military, Executive Privacy, Travel & Data Security, Anti-Hacking Anti-Tracking Anti-Spying Assurance

This device works as advertise. I put the phone in the bag and tried calling it with my other phone and it went straight to voicemail. It literally blocks all signals.

Works well for blocking sun.

They actually Work. Make sure they are wrapped properly around the phone or IPAD. At first I thought they didnt work but I folded the material around my phone and waited for 3minute, when I brought out my phone it stated NO SERVICE! I was elated. This is the only time no service sounded so good!

This is a serious product, with serious engineering. They produce some fine and interesting products.

They seem to work with cell phone test, nothing got through. I bought small ones for my hearing aids to protect them as well.

Ease of Use

Outstanding quality, does what it says.

This bag is well constructed and did substantially reduce the WiFi and Bluetooth signals to the various: Acer, RCA and Toshiba tablets I placed within it. In previous attempts even 5 layers of aluminum foil fully closed did not fully block WiFi on 2.4GHz and 5GHz within 5 feet of my access point. At most, grounded, I got 40-50dB of protection with common aluminum foil so connection was still possible. This bag causes enough loss to force disconnect even next to the stock omni antennas on my Asus AP with the amplifiers turned fully up with non-stock firmware. I suppose someone could even get the larger bags and layer them for even greater protection. This bag fits neatly inside a Stealth gun safe from Deans Safe with the center foam layer removed. My only draw back I see is that the bag makes the outside length and width of the tablet larger because of the way the seams are constructed. Saved me the effort of buying the radar absorbing material and making a bag myself: so great product at this price and no doubt I will buy more at some point.

Ya habia probado uno antes, que me regalaron. Compre mas grandes ahora , ya les contare como me va.

Does what I wanted it to do. What more can you ask for?
