Product review (5 stars): Easy install. High flowing. Maintence free, so far.
I like thet the flappers move pretty easily. So when the dryer is on they are pretty much wide open allowing moist drier air to exit without anything for lint to get caught on. When the drier is off the flappers shut nicely and appear to protect well from rodent entry. Ill be watching to see how this product hold up over time. If somehow the flaps got stuck open or broke off, it would be an entry point for small animals
