Purchased these in February 2023 lovely pouch and good quality and we have used it ever since but unfortunately it has now stopped blocking the signal and I can now open and start my car with it still in the pouch. There was no mention of this on the website. So be aware that they obviously do wear out with time maybe check after a year and purchase a new one if necessary.
Excellent!!!
** Tested ** My car will not Auto Unlock whilst in the bag!!!

complete satisfaction.

My car has not been nicked so far
Fantastic product
Bought this back in April 2023 and worked great when i did the checks but noticed recently that it stopped working. Couldn’t see this on the website that these will wear out over time, might be worth mentioning so people have an idea. I’ve had to buy another pair.
Great product. Does the job perfectly
A high quality product that definitely works.
Good product. Good quality and it works.
