from experience a friend of mine had a field of those style bunkers (fan w/battery setup) and the fans go bad, get paint in the motor's, batteries die or don't hold charge in tournaments. it was alot more hassle then just using a blower. takes longer if you have a half inflated bunker to get it up again too. you have to unzip them, switch batteries and wait for them to air up. then you gotta think of the obvious, usual holes in the bunkers, ect...
