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, winning awards for it's exceptional quality and performance, as well as achieving the coveted Secured By Design Police Preferred Specification.
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.

Excellent product and speedy delivery
After being the victim of a cyber attack, I needed something that would block signals from my hacked phone until I could get it professionally wiped, and to protect my new phone - these pouches are awesome as they stop everything, not just Bluetooth and NFC. I have bought several; my only slight gripe is that my S21 Plus with a protective case only just fits inside and it's a bit of a squeeze, so they could be very slightly larger. Otherwise, top marks!
Very quick delivery and the product does exactly what it's supposed to do. It's very efficent even up to the car there's no signal. Highly recommended
