Review on Silent Pocket Faraday Bag Smartphone Sleeve: Ultimate Signal Blocking Shield for Travel & Privacy - Leather/Waterproof Nylon, Anti-Hacking - iPhone, Samsung Galaxy & More - Multiple Colors by Tyler Munajj

It's expensive but I like the design. Besides, it works. The clasp is awesome and I expect that since the protective fabric flexes minimally it will be more durable than others. You don't have to fold like the others above. This passes my preliminary tests: 1) 1.9GHz cordless phone a foot from base 2) Wi-Fi at 2.4GHz and 5.8GHz, -29dBm and -40dBm respectively 3) Cellular calls on 4G with a signal strength of 5/ 5. The case is very nice and not too big. I'm not sure why others are selling 9 or 10 inch phone cases. If I had to store FOB car cards or credit cards, I would hide them in a separate case. The moment you access your FOB or CC which is in the same case as your phone, your location can be compromised as the phone is constantly searching for repeaters. (Turn off your phone to save battery). I should also note that when testing WiFi with video streaming, some settings buffer quickly, so you might think the product isn't working properly. 1080p streaming should stop pretty quickly. Many people also refer to GPS as a means of location and include within it (although not the actual "GPS") location reports recorded by repeaters/cell towers - these can be quite accurate! There is a record of most places you visit with your phone. I reserve the right to change this rating but for now I am happy with the purchase. Hope that helps.
