Excellent Product & Good Value
Well made and sturdy material with a secure velcro closure. It has a handy ring on the back for a lanyard. As it's a two pack it accomodates my keys in one and my phone in the other. It is excellent value.

Everyone should buy these.
Everyone should buy one of these. They block signals very well. As a breakdown mechanic doing battery tests there great to make the key fobs disappear enabling the vehicle to shut down completely. Great for fault finding as well. Battery drains etc. Tried and tested. Full WiFi signal and full mobile phone signal. Put the phone in and it’s dead. Tried this on 2 different networks. Renate and Dacia keys tested. No signals. Alarm fob for home tested. Not seen. Chip and pin device also does not see the card or phone when you activate it and slip it in. These 2 pouches seem well made and will be a fantastic help to my trade. Product seems well made and comes with 2 pouches. There are 2 compartments in each pouch. Use the rear pouch for protection. Fits iPhone 15pro max with large case fitted. All current car keys will fit in this product.

Outstanding!
With all of the hype over keyless cars being a security risk, they are a real comfort. Just bought a new keyless Volvo so we felt quite vulnerable. I tested the pouch by sitting inside the car and it blocked 100%. Also big enough to take a mobile and tested by buddying next to my wife’s mobile and it totally blocked the connection. Great product.

A device to deter car thieves.
After watching a program about thieves targeting key fobs with a device that can detect a key fob and then start a vehicle without the key fob. I decided to buy this item. Works perfectly.
