Yup, we have two sizes of the 02Cool fans (two each). They work great and are quiet. What a relief when there is no air conditioning!!

Plus my wife has one small one she wears around her neck almost daily. It is her "work" companion to keep her cool.

A spray bottle of water to mist oneself combined with the breeze of a battery operated fan can make the difference between sweating and horrible suffering and being in a lazy bliss on a couch when the power is out.
