5.0 out of 5 stars Fast, cheap, works as described
Verified PurchaseA friend recommended this to me and I am very glad that he did. It came super fast, ordered it yesterday afternoon it showed up by noon today. I didn't read the description very well, I thought I was only buying one, but would have purchased a second one eventually, and it felt like a bonus, so, yay! It feels like it will hold up for some time, even if I'm a little rough on it. It fit my phone perfectly, I could easily fold it up and take it with me and use it as needed. I tested them out and they work just as intended, when calling my phone it says dialing for almost a minute before going straight to voicemail. The first time, I forgot to turn my screen off and I was accidentally touching the screen all over, so I avoided that the second time, but both bags blocked the calls. Excellent product!

5.0 out of 5 stars They work
Verified PurchaseThese bags stop radio waves, so your phone disappears off the global grid. Even when you turn off your phone it usually is not all the way off, and continues to contact the network from time to time. In the past one could take out the battery, but modern phones do not offer that freedom. If you would like for your phone to be quiet, and not to be tracked these are the containers for it.
Some people think it is a good idea to be off the grid from time to time just so there is not an expectation that you are always available. Some folks are worried about spyware that continues to contact the network even when you think you turned off the phone. Some journalists and politically active folks worry about this. In any event, these bags are "Faraday cages" and trap electromagnetic energy. Obviously you cannot receive or make calls when the phones are inside. Nor can you get texts nor have it search for WiFi. Low cost and effective, and much better than aluminum foil.
(I do not know if aluminum foil hats stop brain waves, but that is another topic. ;-)

5.0 out of 5 stars The “Cellphone Vault” to stop spam calls.
Verified PurchaseKeep your cellphone safe! I have one and I take it with me when I’m away from my apartment. You place your phone inside the bag and it is like a “vault” for your cellphone. I purchased mine last year because I was getting a spam caller who could text me and call me no matter what I did or where I was located. I blocked him and before I got my black bag he managed to get through. I looked on 鶹 (the only online retailer I trust) and found this black bag. It works great. I have never heard from him again…Peace of mind. 🥰
