Having previously bought the large size defender I decided to buy the mini one. Seems to work equally well as the larger one.
Great pouch works well so far
Exactly what I needed works perfect
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.
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.
Fast delivery, seems to work well good value for money,would recommend
This is just what I wanted and I have attached it to my keyring. It’s made me feel more secure with my new car
The two defenders ordered replaced two that I have had for some years. They are an excellent product.
Great signal blocker key pouch, works well, delivered promptly at a good price. Many thanks.
Would have give it 5 stars if it had a front compartment
