2 Pack Faraday bags for Phones Faraday key fob Protector Signal Blocking Pouch Faraday Bags EMP Proof, Cell Phone Signal Jammer Faraday cage Car Key/WiFi/RFID/GPS Signal Blocker with Reflective Strip

These Faraday bags are a practical way to protect my devices from unwanted signals. The two different sizes are useful for storing my phone and car key fob. The material feels durable, and the double roll design with Velcro closure keeps everything secure. I appreciate the reflective strip on the larger bag, which adds visibility in low-light conditions. The bags effectively block signals, giving me peace of mind that my devices are protected from hacking or tracking. The waterproof and fireproof materials are a nice safety feature. They're easy to carry, and they seem well-made. It's a simple way to add an extra layer of security.

I can't technically speak to the functionality of these faraday bags - they're for preventative means. But I will say that I do like them and feel a bit more at piece having my keys & phone stuffed in them. That's my only issue - they look bigger than in reality. Thick material, perhaps. I do have somewhat bulky keys and it took a minute to stuff it all in the key bag. The cellphone bag is also a tight space, but it does fit.

This set of RF proof Faraday bags are made very well and have been tested to work. For the larger bag, I put a Samsung S23 in it and tried to call it, with negative results. I also tried to text it, with the same negative results. Then I made a call with it, put it in the bag, and the call dropped. For the small bag, I used an AirTag, and tracking app showed up blank at the same time as it was put in the bottom of the bag, even before I closed the flap, an hour later. When I took the AirTag out of the smaller bag, it showed up again in tracking app. The only thing I didn't like about this set is the exterior finish of the larger bag. It has a somewhat tacky feel and is a dust magnet. It is easy to clean with a damp cloth, but I just don't enjoy the tactile feel of it. Worth taking a star? No way, because these bags actually work, and block the signal, for a very reasonable price. Five Star Faraday Bag Set

These are great bags to block signals. To test, I made a phone call, then dropped the phone in one of these bags, and the phone signal disconnected. I had someone call me with the phone in the bag, but not happening. Also, since no signal is broadcast, any "find my phone" type of app will not find your phone in the bag. Works perfectly. The bags are thick and sturdy, but be sure to measure what you want to put in these bags before purchasing because these aren't huge. No complaints here - I'm happy they do the job at what seems like a reasonable price.

Both the bags work as advertised but they are very small. I believe they are intended to reasonably fit inside a purse, backpack or even pant's pockets. Unfortunately, that makes them so small, it's difficult to fit items into the Faraday pouch. They work but won't hold much beyond a key fob or single cell phone.

I have a small compact Bluetooth player hooked up to a speaker I hit play waited for the music to start, and I inserted the player inside the bag and closed it at which time connection to the Bluetooth speaker was lost This is the only way I have a testing this product and it did block the signal. Because of that I’m given it five stars

With newer cars, you can't leave backup key fob in the car, because it won't let you lock the car with the key inside. These Faraday bags let you put a backup key fob inside, hide in car, then, if you lose your key, you get AAA to open car, get hidden fob out of bag and off you go.

Not sure how well they really work, but it seems well made and my phone couldn’t receive the calls while inside.
