Looks well made and hopefully will provide the degree of protection required (still to be tested)
These are the second set of pouches we have bought. The first set lasted approximately 5 years but eventually the velcro gives up allowing for signals to penetrate them. I am very pleased with them as they do work and some of my family have also bought them on my recommendation.
Excellent product – lives up to it’s reviews and very good price.
works well
Can’t fault the product, has a high quality look and feel.
Great product to protect your car from thieves who use scanners to pick up signals from your keyless car fob. Also blocks mobile phone signal when your phone is placed inside.
It works but it is a bit big just for keys
Was delivered very quickly. Good size for me to find in my handbag. Thankyou
Does exactly what it says on the webb site nice and neat would recommend this poch
These are really good and they work. They were recommended by the Police in our area as there had been a lot of car thefts recently. I keep one in my hand bag for when I’m out and about and one indoors so my car key signal cannot be picked up by anyone outside my house. You really do have to take it out of the pouch for the car key to open the car door even if holding pouch in your hand. I thoroughly recommend these Faraday Pouches.
