The pouches are smart and work well. Well made, easy to use and there is plenty of room for keys. We have recommended them to friends who have also purchases some.

Good quality cases to protect car keys and phone from being interfered with by thieves, basically a Fahrenheit cage.

Works great! Stood right next to the car even with the pouch open it cuts the radio signal. Tried my phone out of curiosity and it only cut off the bluetooth when I closed the pouch. But the fact my phone fits in is the only reason I don’t like it. It is the size of my phone, I was expecting something big enough for just my keys. It doesn’t exactly slip into your pocket.

These work as required to block the signal. Far better than previous smaller ones bought else where.
