Review on 20X15In Faraday Bag For Laptops, Phones & Key Fobs: Fireproof, Water Resistant Anti-Theft Pouch With Hacking Blocker (Black) by Prentice Fossett

My car has keyless entry and start. I have heard of some neighbors that have had their cars broken into without sign of forced entry so I went out looking for a Faraday Bag. I keep my keys in my smallish purse and just put the whole purse in this bag when not in use.This bag successfully blocks all signals even right up next to the car. I also tested this bag by putting my phone inside and attempting to call it - nothing made it through. Highly recommended!
