Faraday Bag 4 Pack – Waterproof & Fireproof Signal Blocking Pouch for Laptop, Tablet, Phone, Car Key – Anti-Theft & Anti-Tracking Faraday Cage Sleeve

These things are great. Firm, strong and the velcro works great.I would recommend especially for the price point. I have tested these with wifi, bluetooth and cell rf signals. All pass the test. Great for what they are. Would recommend.

They work as described, the price was reasonable, and the quality is very good. I have a large phone and the phone case fit fine with my case on it. No signals in or out; I checked. I recommend this product. 👍👍

They work great you can put you phone no one can call you it will go straight to voice mail you can not track it you can put your keys in it and walk up to your car and it will not work until you take it out

Thick and closes good. Hopefully it works but hopefully I dont ever have to use it

Product is as advertised. Bags Seal easily and offer a good combination of sizes for a multitude of different items that you want to protect. The Gage of the material seems heavy and durable. If I ever have a fire or if a solar flare knocks out the power grid I will follow up on my review and let you know how it held.

I ordered these wondering if they worked but figuring I could return them if they didn’t. After confirming that a cellphone couldn’t be contacted while in any of them I wrote this review and gave them five stars. The sizes are a good fit for a cellphone, tablet, iPad and 17” laptop. I would buy them again.

They work as advertised

These bags are complete garbage. Before I trust them to the zombie apocalypse, I ran 2 simple tests: 1) How "waterproof" they are, and 2) can a simple WiFi/cellular signal get through. It failed both tests. A simple sniff-test with one's basic logic can show how the "waterproof" concept is laughable on it's face. Look for yourself at the directions given on how to seal the contents. Fold the bag so that the Velcro makes it waterproof? Are you kidding me? Velcro can't seal out the water! The second test was unnecessary, but I did it anyway, just to show that this thing couldn't keep water out - what kind of chance does a radio wave have in comparison? The radio-wave test was simple: make a call, turn the speaker on, "seal" my phone inside the bag, and just listen. If the call doesn't immediately disconnect, then the radio wave can leak out, and therefore, it isn't able to pass the ONE test that makes it a Faraday bag. It failed that test too. No need to try to find out if it is "fireproof." Run! Run as far away from this steaming pile of bovine excrement as you can muster.

Funktioniert bei mir nicht.
