Review on Pacsafe RFIDsafe Passport Protector Black by Laura Jenkins

I received this case in the last few days. I bought it to protect my car from burglary. I have a newer car with key fobs that should only be in close proximity to the car and when I touch the doorknob the car opens. Since it's an RF blocking case, I figured it would block the signals my car uses to communicate with the fobs. I was wrong, I put my key rings in this bag and tried to open the car by touching the door handle. The car unlocks as if there were no difference. After trying a few things I found that the single was not blocked by the pocket. It's possible that the wavelength used by the car and fobs is very different from RFID, but I'm wondering if this bag blocks any RF signals? Do not use this pouch if you want to block the signals used by the keyfobs. more than i thought. Looks like it will hold up well with use.
