I have had this vent installed for over 15 years and it still operates fine. The doors stay closed when the fan isn't on, and open when it is. There was only one time when one of the doors bound and wouldn't close, but it was easy enough to unstick. I would recommend this to anyone. Sorry, but it has been so long since I installed it, I cant remember how hard or easy it was.
This is used in S.E. Michigan, so the climate is extremely variable throughout the year.

Plastic everything. Mounting cumbersome to do. Flaps inside unit warp and do not close or open properly. Texas heat destroys thin plastic flaps. Bugs and scorpions wil travel thru with ease . It happened to mine.

Rated 4.0 out of 5.0 by SteveP Performs as expected and very good value.
Good product. Installation instructions virtually useless. Not that it was complex but the position of the mounting clips for the vent line matter if you actually want the vent flaps to close and open when the fan goes on. Other than that it is a great product and easy to install.
