Seems if you scroll around shopping websites and look at the negative reviews you always see people saying things like “never worked at all” or “stopped working soon after”.
It can’t really be that involved to line a small enclosure with some metal fibers, can it?

Last time I went to DefCon, the SLNT Bags were petty popular. I didn’t buy one myself so I can’t speak to their effectiveness, but if the DefCon crowd trusts them I think they’re probably at least worth looking into.
I am not sure if I would trust a company that claims a glorified fanny pack will protect your health from EMF radiation.
Any chip packet (you know, like a Doritos packet) , or your fridge. Try a chip packet in the fridge, that should stop it.
Haven’t tried the microwave, but maybe that’s an option too.
I saw a speaker at Black Hat once break down some big failures in international espionage, and one instance he cited was CIA agents thinking they could use a Doritos bag as a Faraday cage.
Works depending on how you do it, how many bags you use, where you are, and what the signal stength is.

Enough chip packets will block anything.
What are you trying to accomplish? Prevent RFID tags in a wallet from being read?
Ah, you know, just throw a device in that communicates anywhere from 40 KHz to 40 GHz so that it never communicates until I take it out.
Keep my garage fob from going off, fuck with googlemaps, the works.
The most reliable way to know if a Faraday bag works is to test it yourself - put your phone inside, call it, and if it doesn’t ring or go straight to voicemail, it’s blocking signals effectivley.
Well yes but in that case you have to keep buying and testing bags until you find one you like.
So, alternatively, I asked if anybody here has used or reccomends them.
