Schneier - Bogus Security Technology: An Anti-5G USB Stick

The 5GBioShield sells for £339.60, and the description sounds like snake oil:

...its website, which describes it as a USB key that "provides protection for your home and family, thanks to the wearable holographic nano-layer catalyser, which can be worn or placed near to a smartphone or any other electrical, radiation or EMF [electromagnetic field] emitting device".

"Through a process of quantum oscillation, the 5GBioShield USB key balances and re-harmonises the disturbing frequencies arising from the electric fog induced by devices, such as laptops, cordless phones, wi-fi, tablets, et cetera," it adds.

Turns out that it's just a regular USB stick.
