Just ideal for pocket and also indoors
The wonderfully inefficient Royal mail managed to lose the order but when I queried the delay two more pouches were sent out straight away. No hassle and brilliant service. AND the pouches work superbly. Place your keys on the bonnet in the pouch and the car is secure. Excellent!
No need to have sleepless nights worrying if your car will be their when you get up in the morning.
It works

Very pleased with the pouch
Seems to be well made. Successfully blocks car key signal.
Very quick delivery and the product does exactly what it’s supposed to do. It’s very efficent even up to the car there’s no signal. Highly recommended
Does what it says on the tin. Good price
Received, a couple of days after an email saying order completed. I’ve previously bought several of these pouches from the well known auction site. ALL worked well on receipt and yet when I checked the signal blockers capability around six or seven weeks later, non of the pouches work. I have purchased cheap and expensive pouches and found non block any singles after 6 or 7 weeks. I wait to see if this pouch is any different. It looks nice and it works well on day one. I live in hope………..🤞
