OFFGRID Cell Phone Faraday Bags - Premium EMP Proof Faraday Bags - Device Shielding Data Security for Signal Blocking & Anti-Spy Protection. Faraday Bags for Cell Phones, Tablets and Laptops

Turned on the XM Radio on my phone placed it in the bag still played it was still receiving a signal. Product does not work

Not good quality. Hard to use camera with this. High price and bad value. Would not recommend!!

Very nice product. Magnetic fold over closure.

I used to eat some head Cheryl people try to call and of course the number was unreachable. I also took a short road trip and use the Ferriday envelope and it was adequate to block applications and signals. Knock on wood I hope it continues to maintain its integrity but as it stands right now they are good to go.

I think it does what it says its supposed to.

The description said its wrinkle-free material... NOT TRUE!! It looked messy once I used it.

Be careful; I specifically ordered for an I phone pro max 12. This is too big!

Me gusta que es ligera y compacta, aun asi se ve de buena calidad los materiales, el color y el diseño son muy buenos.

This is great for blocking signals to and from your cellphone or other device. To test this out, we placed an iPhone 8 in there, closed up the bag, and sent several text and email messages as well as calling the phone.

FIRST THING I DID WAS TEST IT. PUT IT IN THE BAG AND CALLED MY I PHONE FROM THREE LANDLINES.
