Product review (3 stars): Installation directions very unclear
It looks great once installed. But install directions are terrible.  Searched for a video but none exactly like this one.  Very heavy so have a few strong bodies to hold it while it is being mounted.  We built a support for it to be mounted to as the hardware provided was questionable to hold this up.  So price is great and fan is rather quiet and we love the recirc. option (carbon filters sold and ship separately) .  But plan to make up for it by buying extra mounting hardware and pay a few extra bodies to get this to the ceiling.
