    Amazing product!
  

*by D***N on Reviewed in the United Kingdom on 23 May 2019*

So let me set the scene....We recently moved on to a new estate that seemed so perfect at first, that was until we installed our night vision cameras which showed us a horrible sight.This was someone being able to get in to not only my car, but my partners and many others on the estate despite them being locked.  Initially I thought I'd been stupid enough to leave it unlocked until I double and triple checked before I went to bed the next night and the same thing happened again, now these people weren't trying to steal the cars just some of the possessions from inside.So I did a bit of research and it turns out that some cars that have keyless entry the signal can be amplified using a device to trick your car in to thinking the key is close by and unlock the doors/start the engine, now this horrified me that someone could do this, so I quickly checked what I could do to prevent this and quickly found these kind of pouches/wallets worked, I was a bit dubious but thought I'd give it a try, and lo and behold it worked an absolute treat, the guy that tried to get in to our car again found quite quickly it didn't work and my camera now made an alarm sound when someone entered into it's field of vision late at night so we were able to secure our belongings and scare him off too!

    Works perfectly
  

*by D***L on Reviewed in the United Kingdom on 11 February 2019*

Look and feel well made. There are 2 sections inside the pouch and you need to make sure that you put the keys, phone or whatever it to have it's signal blocked in the correct section.My Volvo wouldn't unlock when the keys were inside the pouch and the key wasn't detected even when sitting inside the car, so it wouldn't start either.The liner appears to be double up, so maybe this is why it is more effective than other methods I've tried. Also hopefully this means it will last longer as well.

    Worked perfectly when tried
  

*by Q***R on Reviewed in the United Kingdom on 18 April 2020*

I put a mobile phone in following the manufacturer's instructions and it was uncontactable for calls. It did not show a missed call. It was not visible via bluetooth either. The Faraday cage clearly blocks any electronic or radio communication. Using messaging services such as whatsapp does not work whilst the phone is in the cage but the message is waiting when the phone is removed from the bag. This test shows that cards, keys and so on are well isolated. The bag could be used without the cage for carrying the phone so it protects it as well when not wishing to physically use it. A 5.2 inch phone with a protective case fits in easily but it is not over large and keys, cards etc can be just as well protected. Since you get 2 pouches for your money this is a pretty good deal; you can use both at the same time or keep one as a spare.The product appears well made and looks good. Because this review is of a new product I cannot comment on durability which is very important for something which is security orientated. Perhaps it would be a good idea to check from time to time that it is still effective by putting a phone in it and then trying to call it.Overall I am very impressed initially.
