Bests & Worsts Reviews from Amazon

I purchased this Mission Darkness Faraday Bag because I was concerned about the growing trend of theft of vehicles with keyless ignition via 'relay attacks' where outside your home thieves grab the signal being transmitted by a nearby key fob inside the home using a special receiver, and then that receiver relays that signal to the car, allowing the thieves to unlock it and/or start the ignition. I put both key fobs in the Mission Darkness Faraday Bag, and tried to start the Nissan Maxima several times via the push button start while sitting in the driver's seat with the bag in my lap. 100% successful tests! And then decided to test the bag to see if it blocked WiFi and phone signals as well, so I started a test on the Mission Darkness app, placed the phone in the bag and sealed it. Per the attached screenshot, you can visiually determine the exact moment when I placed the Sprint LTE mobile phone in the bag. Another successful test. I highly recommend this product!
