Great fan, the second one of this type we have purchased. It helps keep the bedroom cooler without a doubt, its quiet and the remote makes it very simple to change or switch on/off from the bed. We have had this running all night and it doesn't disturb your sleep, in fact the low hum noise sends you off!!
I purchased this primarily to blow water out of the car wheels and seals when washing it which helps keep water marks down. its also useful for blowing the garage floors and pathways after cutting the grass but much more than that and it wont handle it. Good for cleaning the dust out of the back of the van too.
Variable (3) speed is good although I can imagine most people will use the highest speed (#3)
