Some Amazon consumers have purchased what are described as Faraday Cages, but which can more accurately be described as simple wire-mesh containers. A Faraday Cage is an enclosure intended to block electromagnetic signals, one example of which is WiFi.
The products are advertised as having the ability to deflect 5G signals, which the purchasers believe cause harm to humans. This is a misnomer, as 5G signals are too low on the EMF spectrum to do us damage.
The containers “work” in the sense that signals are deflected when routers are placed inside them. But those signals are necessary for WiFi to function. One would get the same self-defeating effect by unplugging the router or foregoing Internet use altogether.
According to Matthew Willie at Input, these clueless consumers are leaving negative reviews about the cages, or at least they are when not employing the cages since there’s no getting online when one does so. To be clear, consumers are placing routers in the cages, then getting steamed when the cage blocks the signal the customers are hoping to block! Despite all their rage, they should just take a bat to their cage.
