DefenderShield MOLLE Faraday Bag

- Made in USA- MOLLE straps have no velcro- Double zipper top opening- Slim window pocket on front, 1" velcro tab closure- Inside liner not tacked in, it can come fully out- No access to inside the bag but outside the liner, if you know what I meanI failed to realize that I wouldn't know how to test this. I know this subject is rife with scams and misinformation so, short of being able to test it, I looked into the company that makes it.By their About blurb on their website, they seem to be aimed at EMF/EMP shield in general, as in your cell phone (all digital items) emit electromagnetic fields. Founded in 2011 in the US, a father and son started it.I came at this from a prepper's perspective. A Faraday cage is this only thing that could stop an EMP. There's a lot of claims out there these days and I can't pretend I understand it all, but basically, IF (and that's a big question) there's an EMP near enough, it'll fry any connected electronics unless they're in a sufficiently thick metal enclosure. (Another school of thought is an EMP will knock most electronics off but won't fry circuits, so they could be turned back on)The chances of it are subject to lots of interpretation but eh, being a prepper means you try to be ready for anything, so...My friend gave an easy idea to test. While in the bag, my cell doesn't get signal at all. It goes straight to voicemail. My garage door opener also won't work. No Bluetooth item works, either.So, whether it's going to be needed or not, who knows, but I'll at least have a pouch full of solar banks and rechargeable flashlights safe at hand heh and that's a 5 star for apparent effectiveness and sturdy build.Don't forget to use the Smile.Amazon.com address - It's an Amazon program where many everyday things you buy will generate a small donation from Amazon to the charity of your choice at no cost to you.

Smaller than expected but seems to work.

I am actively reviewing this product. Thus far, I’ve been able to block smartphone WiFi, Bluetooth and LTE, as well as FRS frequencies used for “walkie talkies”.This product seems solid, well built and durable. If you are purchasing this product for operational security, please ensure you test this product for your specific use case PRIOR to use in the field.The window in this product is NOT inside the faraday portion of the bag - you cannot place a device in this bag and use it through the window. The window is more for use with maps, IDs or other items you would like to maintain visual access to while the bag is closed.I recommend this passive security product for anyone who wishes to block communication between devices inside the bag and the external networks it connects with.

This Faraday bag is great. It stopped almost all of my signal. I did hear the phone beep once with find my phone but then it went away. Good if you need to block a phone.

I use this faraday bag to keep car keys for my new vehicle safe from burglars. Works well so far although it's only been a week since I received this item. Bag is rather large for this purpose.I have peace of mind because of this bag blocks more signals than other products I have read about.
