Product review (4 stars): Wouldn't recommend using it in your cellar if you don't have ...
Bought for reason of mice sneaking in thru the outside dryer vent no matter if it had a screen or not.  So I decided to close it off and put this down cellar.  I hang my clothes outside during the summer and only use the dryer in the winter.  Wouldn't recommend using it in your cellar if you don't have a dehumidifier going.  You'll end up having mold growing.  Simple to install (female installed it).  I keep it on the floor since if have no where to attach it too!
