Review on Faraday Upgraded Blocking Protector Anti Theft by Gerard Hudson

I really wanted them for both my cars. When they arrived today, I immediately put the keychain from my Genesis in one and took it to my car. With the key fob in my pocket, the car started without hesitation. I locked my car and tried to open it with the key fob in my pocket with the same result. Then he went in, wrapped the bunch of keys in aluminum foil and tried the same thing as before. The car didn't open or respond at all, confirming that the bag didn't work at all. I tried the same thing with the key fob for my Toyota Tundra and got identical results so I am returning the packages for a refund. Revain has done an excellent job with refunds and returns. I'll probably only use aluminum foil for my keychains for now.
