    Well-made and effective. Perhaps a little small for larger car key fobs - but then the full-size Defender Signal Blocker is much too large for car keys! I feel that the built-in key ring is unnecessary.

    Keyless car theft, the result of the modern age looker for the easiest, and possibly laziest ways of doing things. It’s an issue for a number of modern cars, this little pouch aims to reduce that risk. To be fair it works very well, if my key is in the pouch and in the car, the car doesn’t recognise it. It could do with being ever so slightly bigger, but my key fits if very snug.
