These devices make grating Parmesan and other European hard cheeses a breeze, compared to a plane or box grater. You can use any reasonably sized blocks of cheese (1/2″-2″). Soft cheeses do not work well in this grater — they become stuck in the grate barrel and become glued to the internal structure.
If you look closely you can see a dog being cooled by this Endless Breeze fan. These portable 12V fans plug into a cigarette-lighter style plug. They only draw 2.58 Amps when on high speed. See more info here. They are available from Amazon for $60. Thanks for the photo Brenda.
