Faraday Defense 3 Pack Mega Kit NX3 Triple-Layer Cyber Fabric Faraday Bags - Fast, Easy Access for Device Shielding - Protect Data and Devices from Hacking, Tracking, EMP

Works as advertised.

This is essentially a glorified aluminum foil zip lock bag (I don't know if this particular bag uses aluminum or some other material). But I wouldn't trust myself to be able to wrap my electronics properly with aluminum (note, if you leave a gap somewhere, your electronics might get fried when an EMP comes). Also if I need to access it, it'll be a pain. I saw a YouTube video by the EMP Doctor where he put a radio receiver inside the bag to measure the radio signals it picks up and showed these bags did the best, which is why I pulled the trigger and bought these bags. I also tested each bag when I got home using the following steps: 1. Turn my cellphone on loud 2. Ask someone to call me (alternatively you can use the "Locate my phone" feature available on most phones these days) 3. My phone rings on loud and receives the call. 4. Put the phone now in the bag and seal it 5. Have someone call again 6. No ring from my phone. After I took my phone out of the bag, it actually showed for a few seconds that I had 0 bars and no WiFi signal which is pretty cool. So this thing definitely works. I'm putting my emergency radio in one of these before placing it in the bug out bag. I also have an empty one in my bug out bag for storing my phone. The smallest size is good for phones. The medium is good for tablets or something like an emergency radio. The large one is for laptops. I personally would've preferred to have more of the small or medium bags. Overall, these are great, but I do wish they were cheaper. Although if SHTF, I'd pay anything to make sure my emergency radio and cellphone are still working.

Good for you for thinking ahead and planning for worst case scenarios. That usually includes AM/FM/NOAA radios, external USB drives, Ham radios, and a tablet pre-loaded with emergency themed documents. Now shield them (with the batteries unloaded) in these bags. My own tests confirmed complete isolation and a better chance against a low-yield EMP.

Finally a faraday bag that actually works it’s worth the price easy enough to use and has all different sizes

I’ve been getting these for an over year now. My old ones have seems like a zip lock. But these are much better with the Velcro. I gotta get more of them to replace the old ones. Highly recommend for anyone looking for protection for their drives
