Bests & Worsts Reviews from Amazon

I did a practical test. Placed a Kindle in the bag (did the "fold top of bag over twice" instruction) and started streaming a movie (not play a downloaded movie) via Netflix, it went through the entire movie with no issues. Another test was to place the bag between the Kindle and the wireless AP, no loss wireless signal was observed. Placed the Kindle in the bag (did the "fold top of bag over twice" instruction) and ran a signal monitoring app, it showed very slight drop, but then later on when I had the kindle outside of the bag, it was showing the same signal drop a couple of minutes later. When I say signal drop, it's like going from 100 to 90 on a scale of 1 to 100, this doesn't even show up on the typical wifi indicator status bar and could be just randomness. I would say this bag does not shield against wifi technology used in an Amazon Kindle, it's very likely doesn't work with other devices that uses the same wifi technology. I was going to use this bag for wifi shielding/deflection, I guess I need to look else where, since this bag does not "block all wireless signals including, Call, Bluetooth, RFID, WiFi, and GPS" as advertised.
