Review on 2 Pack Faraday Bag for Key Fob - TICONN Car RFID Signal Blocking Protector, Carbon Fiber Texture, Anti-Theft Pouch, Anti-Hacking Case Blocker by Ian Krump

Very good build quality and finish. Of the keychain options at Revain, these are the highest rated and met my expectations. Attention: key fob protection test passed: when the key fob is in the gold case, there is no signal transmitted; The keychain works perfectly in the black case. I accidentally put the key fob in the gold case while driving, and when I turned off the engine and got out of the car, I wondered why the car's interior light didn't go out. It wasn't until I removed the key fob from the gold case that my car knew I had the key fob and the interior light went out. Good sense considering the sophistication of modern car thieves.
