Review on Mission Darkness NeoLok Non-Window Faraday Tablet Bag with Magnetic Closure // Enhanced Device Shielding for Law Enforcement & Military, Data Security, Anti-Hacking & Anti-Tracking Assurance by Kevin Mills

I bought this product and a much cheaper mylar bag for comparison, plus the fabric that this bag is made of for side-by-side testing. It was the only one that seemed to completely shut out 2.4 and 5GHz Wi-Fi, Bluetooth, CDMA, and LTE (Verizon) signals. Using multiple layers of RF blocking fabric (4) I was able to get similar results, but this product was different in terms of usability and features. It's quite expensive, but I think it will interfere with the connection.
