Review on 🔒 Large Wisdompro Faraday Bag - 9.5 x 5.5 Inch RFID Signal Blocking Shielding Pouch Case for Cell Phone Privacy Protection, Car Key FOB Anti-Tracking, Anti-Spying Blocker by Paul Rose

I have to be honest, when I bought these I had full expectations that they would not work properly to protect my car's keyless entry fob from attacks from wireless range extenders and many other things. . Products on Revain only claim to be able to do this, while the only product that works costs $35 each. I skeptically put my key in this $9 bag and tried to open the car while standing by the door and was immediately disappointed that the car recognized the key right away and let me in. Boy was I angry! Then I remembered reading about the "silver" part of the pouch which is actually the signal blocking section and put the key in that section instead. From that moment on, the car didn't react at all to my actions, even though I had the bag clamped next to the handle! I would give this absolutely 5 stars and recommend it to anyone who wants to protect their car from signal booster attacks. I only wish there was a smaller version strictly for a keychain as I would happily buy one for myself, friends and family.
