Product review (5 stars): Great product
This is the second set of vent closures I have bought from Amazon. They are simple to install and work very well. They keep birds and bugs out of the vent, and help to trap any lint that makes it past the lint screen in the dryer. My only complaint is that I have to replace them every few years. Mine are in a spot that is in direct sunlight all day, and the ultraviolet light and heat from the sun both take their toll on the closures. They start to discolor and crack after a few years, hence the need for replacement. I am sure if you have them in a place that is shady, they would last a lot longer. Still, a great value for the money.
