Product review (5 stars): keeps mice out
It's good . Stopped the cold from comming into my bathroom. It's plastic without a wall tube. It's paintable. It's good if you don't care about how your house looks. I have this on the house until I can get 7 stainless steel commercial quality vents installed throughout. But this is a great 20 dollar solution. Also stopped the mice from getting in. A huge plus for critter intrusion.
