The Defender Signal Blocker is a high-quality faraday pouch; dual-purpose vehicle fob and mobile phone storage pouch.
The dual-purpose nature of the Signal Blocker sees it combat two of the biggest security and safety issues: 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 the 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.

Why not check out the Defender Signal Blocker Mini?
It actually does what it says on the tin. Seems to completely block the signal like it says it does. Tried it with two phones linked via mobile hotspot, even sitting on top of the pouch the signal had stopped transmitting from inside. Worth every penny.
Great product provides some assurance against car and phone hackers. Good price too. Win win all round.
Products look well made. Size good; would fit most car keys or phones without being excessive. Bought as a present so cannot comment on how effective they are ( hence reason for only 4 stars) but research before buying showed them to be better than most.
Two pouches in the bag great value and they work very well
Everything I needed at a very good price
These bags really work, well made and a great price.
Does exactly as described.
Great product !
Absolutely brilliant, well made and super effective. My phone goes out of service as soon as it’s inside the case. Service returns about 5 seconds after taking it out again. It’s great for when I want my phone on, but don’t want to be contacted. The bonus of the case is that it also protects against any harmful EMF radiation coming from your phone, especially if you sleep with it anywhere near you at night time. 5 stars! ⭐️⭐️⭐️⭐️⭐️
Product came very quickly, well packaged. Wallet for keys is very well made
