Product review (4 stars): Dryer vent
It looks different from any other vent I ever had but it has been doing a great job so far.  I live on Hilton Head Island and we have squirrels, bugs and lizards that want to crawl into anything that will get them into our house.  The floating centerpiece has successfully locked them out and now I don't have a wire mesh screwed to my house over top of an old style swing vent.  Cleaning the lint out of the wire mesh cover was truly a pain in the neck so I am very happy this is working well.  I gave it a month before I rated it so you can feel confident that this will be a good purchase.
