I ordered 3 of these fans and they did Not come in a manufacturer package, it was strange, they just came in a plain brown box with directions/info that did not even seem to go with the fan.  It makes me a little nervous, seems strange, have not had my builder put the fans up yet, but hopefully they all work.  I do NOT  like buying something that has been removed from original package.  Makes me think its a return product or refurbished and I'm paying for new product.  I'm not happy with this and makes me nervous about other orders.
