Signal Blocking Bag for iPhone 8 - Cell Phone Privacy Protection Anti-tracking Anti-spying Anti radiation Key Pouch Signal Blocker Signal Shielding Wallet Case Handset Function Bag

I can report only on my own experience. This pouch fits my phone perfectly, and under testing with a Trifield 100xe EMF meter, it did block radiation, which only affirmed my experience that no cellular or Wi-Fi signals were able to penetrate. I like that I'm not being microwaved incessantly to the point of cellular disintegration (double entendre inadvertent, but apposite), and I also like that the phone can't broadcast my every phoneme, as I speak it, to all the various and sundry entities that want to hear it (though I believe my conversations would bore even such AI programs as might waste time interpreting the tedious drivel I spout). Still, one likes not to have even completely anodyne discussions broadcast to the entire universe. (I'm not so deluded -- nor should anyone else be -- as not to believe there might still be inextirpable malware, bloatware -- or even firmware -- recording audible signals to memory for subsequent rebroadcast, as long as I can't be bothered to remove the battery and smash the phone ☺... because, obviously, sound still does penetrate the envelope... but for my purposes, 'tis enough, 'twill serve, and 'tis incredibly cheap.)Now, judging from some other reviews, there may (or may not) be some variable quality control, but I've had no problem with the unit sent me. Still blocks calls and incoming and outgoing EMR, as long as the flap is closed.

For quality and price. It’s all worth it. I bought two to keep my keyfob safe from the goons. I tried both with my key fob and my cellphone. When I get next to my car, no signals were detected even if I tried to open the door. Once inside, I turned on my infotainment and tried to play Some apps thru Bluetooth and the car was unable to detect signal from my phone. If you don’t wanna be traced, this is all you need.

This bag fits my Nokia Lumia 640 which is approximately 5.6" X 2.8" X 0.3" according to Amazon specs. The fit is good even while my phone wears the back half of its Evocel phone case. Phone signal down to zero bars while inside the bag. Seems to be made of durable materials. Strong hook and loop closure on the flap. There is a small nylon loop on the back for a lanyard, but no belt loop. Made in China.

It works. No calls or blips or bloops from notifications get through when in it.

when I first received this item it seemed to work fine. After about a month it started to fray and fall apart. I also started to test it with an EMR meter and it was becoming ineffective at blocking the cell phone radiation. I contacted the seller to ask for my money back or a replacement and they said they would send me a replacement which I never received. So for anyone thinking about buying this save your money and buy something that has no negative reviews.

I was a little skeptical about the bag based on the reviews but when I put my phone in the bag, it disappeared electronically. The bag was a good price and it works. Nuf said...

i put my smart phone in this pouch for personal privacy and safety.

Convenient size and works well (as far as I could test).
