Great fan.  The cord could be a little bit longer but I get by with a 12 volt extension cord.  I did have a problem with the first one I received.  The fan blades would rub on the inside of the housing if you tried to move the fan while it was turned on.  I returned the fan and they send me a replacement that works flawlessly.  The fan blows a lot of air and does not draw an excessive amount of power.
