Scroll down a little for the links to pages on mixers, toasters, other kitchen appliances, vacuum cleaners, fans, toasters, irons, radios, etc.

Those old appliances just looked dangerous!

I have 3 of those Zero fans. Not to worry. The motors aren't too powerful, so if you stick your fingers through that "guard", you won't get cut or lose them.
