Review on ClearBags Shielding Electronic Translucent SSO35 by Jeff Drollinger

These are bags. They are crisp and have reasonable build quality for the price. They do NOT have a zipper as advertised, but do have an adhesive strip. They definitely do NOT block normal EMF. Even weak signals pass through the bag as if it never existed. I've tried double packing, folding and rotating to increase the number of layers but to no avail. So RFID signals should have no problem getting through the pockets. Claiming that they review Faraday is a scam. To be fair, maybe they can attenuate some frequencies, but the Faraday Defense claim implies almost complete spectrum coverage. Since they don't list the frequencies they are designed to protect against, their EMI shielding claims are utterly useless. It's possible that they are (I haven't tested) ESD safe, but that's an entirely different claim from EMF. At this point I seriously doubt even the ESD claim.
