Product Details

As seen on BBC One's Rip Off Britain, BBC News, Auto Express and many more... The UK's no.1!

The Defender Signal Blocker is a high quality, dual-purpose vehicle fob and mobile phone storage pouch that is lined with specialist RPF™ material.

Since launching in April 2017, the Defender Signal Blocker has become the best-selling 'faraday bag' available.

The dual purpose nature of the Signal Blocker sees it combat two of the biggest security and safety issues of the day: relay attacks on vehicle fobs and distracted driving caused by mobile phone use. 

When sealed inside the pouch, proximity fobs are fully protected from tech-savvy car thieves, ensuring your vehicle cannot be stolen in this manner. 

Similarly, a sealed mobile phone cannot receive any calls or notifications, leaving a driver free to focus on road, free of distractions. Once removed, all missed alerts pull through to the phone within 5 seconds.

Beware of imitations! The Defender Signal Blocker is the only blocking pouch to feature industry-leading RPF™ material.
