    Defender signal blocker

    Posted by Brian Cuthbertson on 27th Oct 2021

    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.

    Having previously bought the large size defender I decided to buy the mini one. Seems to work equally well as the larger one.
