Product review (5 stars): Best Dryer Vent Available
I have used this vent for several years and it really work better than any other vent I have tried. When It was damaged by a large tree limb, I search for a replacement. I bought my first one in a big box lumber store, which no longer carries it.  I'm am buying yet another for vent I'm placing in my shop. It seals tight when not in use and yet allows air to flow freely when being used. I highly recommend this vent.
