Just looked these up on Amazon.  A great range of devices (and prices).  I
noticed that none of them have a safety screen.  Is that because the fan
speed is so low that they can't injure, or because the fan blades are of a
soft material that will not cause injury, or both?  I have just never seen
a modern fan for air flow comfort that did not have a screen to prevent
inadvertent contact with the blades.
