We find the Endless Breeze to be a superb piece of RV gear. I can understand why it costs more than other 12 volt fans ... you get what you pay for with it.
It moves an extreme amount of air versus the battery power it's consuming, which makes it great for drycamping in warm temperatures when the air conditioning is not quite required.
I made a special extension cord for it so we could use it outside by plugging it into our entertainment center's 12 volt receptacle. Outside we use it for keeping cool when sitting under the awning on warm windless days and for use on an outside dining table to keep the flies away.
This website shows how to make a special mount for it for the ultimate in convenient comfort inside the RV:
