Flutterby™! : WiFi Faraday Cages

What's funnier than people selling Faraday cages for WiFi routers? The 1 star reviews complaining that after putting their WiFi routers inside said Faraday cages their WiFi signal becomes unusable... Also:

Question: Why put your router in a faraday cage when you can accomplish the same goal by throwing the router away and wrapping your head in aluminum foil?

Answer: Thanks for your question. If you wrap your head in aluminum foil then you can't use your router because you can't see. Thanks

So it appears that the sellers are in on the joke, even if the buyers aren't...
