Works really well, I am delighted. I feel the car is much safer now, especially when I park in town.
I found this a brilliant item, better then the last two defenders i have brought from other companies .
A well made product and quick delivery from a professional company. The Mini pouch arriving just before Christmas. (Thank you) The car keys only just fitted inside though – was a bit tight, so the pouch could be a couple of millimetres bigger. Would buy again from this company.
An excellent idea and product. First one given free and so effective we decided to purchase a second one for the other key
Needed some security for my car key as it is a keyless entry vehicle. Seen some reviews for the defender signal blocker case which looked good so I purchased one. Very good price and quick delivery so far seems very affective after a couple of weeks I have had it.
Very nice looking and functional product
Excellent product and service
Read numerous reviews before ordering. Works exactly how it’s supposed to. Like the extra hookring on back and have used for other car security keys. Found hookring to attach car key inside a bit awkward at first but soon got used to it and definitely makes you remember to put key fob inside. Definitely recommend this item
These work really well as good as they say
Amazing – key in pouch in the car and the car still won’t turn on which is exactly what it’s supposed to do. Amazing
