Just the right size to protect my "Military Hand Crank Charger 60W Solar 12 Volt Car Battery Generator Bug Out Kit" including the folding 60watt solar panel. Could not squeeze the plastic case into the faraday bag that contained the hand crank and accessories, but was enoungh room for the individual items that was in the plastic case. Hope that the bag will really work to protect against EMP.

I needed to protect some sensitive electronics from the local office WiFi and Bluetooth signals and the Silent Pocket Faraday Bag has worked well. The construction of the bag is good. I did not test to see how waterproof the bag is but it does have the standard fold down and clip opening that I have seen on other dry bags. Is it really 10 Liter - only when fully open, probably closer to 350 or 400 cubic inches when sealed up tight.

Seems OK. I put my phone inside of it and called it. The call was blocked so it seems like it works.

Very sturdy and completely blocks my phone.

Great signal blocker.

Protection was my goal, and this product delivered it 110%!

The item arrived very promptly and in good condition. The price is very fair. I was impressed with what appears to be a very quality made item, inside and out. The only concern at all is that the picture seems to show a lower outside connection point/loop, as one might clip a strap to (As a second connection point opposite potentially utilizing the loop of the top closure as point one.) Mine does not have that lower connection point/loop. That being said, I am very happy with the purchase and am even considering gifting additional purchases to one or two of my kids (Though they certainly would like to have an additional connection or something that would enable a "Sling Carry" option).
As far as the Faraday cage abilities, one will only know for sure if that is NOT functioning properly, as otherwise you assume it is working. My concern is a Carrington or EMP event. SO...I hope I never know. I am keeping shortwave/HAM Radio transceivers and accessories in mine, but may get another for one for laptop travel etc. I heartily recommend.

Works ok, just a little harder to get closed properly.

I love this thing! It’s perfect for fitting a bunch of electronics into! Tried phoning myself while in the bag - phone instantly lost signal. Amazing! Works exactly as advertised. The only thing is I bought it at twice the price which was a bit pricey. Maybe I’ll get another one now as it’s a very good deal at the current price.

Cuts my phone and tablet off completely from any signals when shut. Works for me
