  • Reliable and effective
Size: Universal Phone Size
Does exactly what it claims. It blocks all signals, including WiFi, Bluetooth, and GPS, as soon as my phone is inside. I tested it with calls and tracking apps, and nothing got through. Feels durable and well-made, with strong stitching and a secure Velcro closure. It’s a good size for most phones and small devices, and it’s easy to use. If you’re looking for solid signal-blocking protection for privacy or security purposes, this is a great choice. Very curious how it would handle an EMP blast though. ... show more

  • Now that most of our pix are digital, this is a means to keep them secure.
Size: Universal Phone Size
Bought to store my zip drives of photos safely. It is great! Holds 3 drives 14TB of images. It's roomy--could hold my iPhone & 2 drives for sure, possibly all 3 also. A little pricey, but it's well made & I feel secure using it.

  • Works as intended
Size: Universal Phone Size
Very lightweight and durable materials used for for this bag. I tested it multiple times with even two phones and worked as intended. Most of these products cost quite a but however it's worth the cost due to the reliability of the materials. The bag is a little too large to carry in your pocket about the size of an iPad, however it's easy to store in a backpack or car. The design is sleek, lightweight, and also offers protection for your devices. Works as intended and will definitely be buying more products from this brand hopefully when they have another sale. ... show more

  • Test it properly with online app.
Size: Universal Phone Size
I was thrilled to get this but figured I'd test it a few times to see if it works. My first test. I connected to a Bluetooth music receiver , I let the music play and then put my phone into this bag. The music stopped. 2nd test.. I had wifi turned off and data turned on, I put phone into bag and sent a text to my phone via pc. No sounds of receiving a text. I took phone out of bag and a few seconds later the text arrived! So far so good. I then turned off data and turned on wifi and repeated the previous test. Worked great! I was going to leave it at that but decided to download the MD Faraday bag testing app. This is kind of contradicting as it makes you let the app have permission to access all aspects of phone including photos. I downloaded it anyway, Started the test, put phone in bag (yes, closed it properly). Waited about 20 seconds and took out the bag. At first this test failed and I jumped the gun and gave a 1 star but I read instructions again. It seems you must take device out of bag and wait about 30 seconds before stopping the test. Each time I did this, it passed with flying colors so it's 5 stars. UPDATE... It's been about 6 weeks of using this bag. It mostly works BUT today I tested it 3 times in a heavy populated area while driving and it failed 3 times. When I got to a less populated area it passed. Shouldn't this either work or not work. Maybe I'm mistaken but I would think it should work when stationary or while driving. Bumping it down a star. ... show more

  • Blocks cell signal, good build quality
Size: Universal Phone Size
Pouch blocks cell phone from getting service. Looks and feels like a quality pouch. You don't really need to velcro all the time, can just fold opening and items are blocked.

  • Works exactly as advertised
Size: Universal Phone Size
Popped my work phone into it, test call went straight to voicemail. If you got folks who need a reminder about boundaries, this will definitely do the job.
