Product review (4 stars): Easy installation, blocks birds from entering vent
Had a birds nest in my bathroom exhaust vent. Had to wait until the eggs hatched before I could remove and install this vent hood. Easy installation, blocks birds from entering vent. I tried the big box stores, and all they had was the crappy one I already had that broke and allowed the birds to enter. Sorry to say but when the baby birds hatched, the cat was close by. :-(. Yay for the cat. :-)
