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?
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.
Sure, but if someone is looking for recommendations for “faraday bags that work”, I wouldn’t recommend “any chip bag” if it needs to be qualified with “it depends on a lot factors”. I’d just recommend an actual faraday bag whose intended purpose is to block a signal.
Yeah, but the problem with that is that they don’t get to eat any potato chips.
Anyways, today’s use case for the person’s post is to block a garage door beeper, so chip packets or a refrigerator should do fine.
…unless they’re also abducting people for extraordinary rendition. Then maybe get the faraday bag.
