Product review (5 stars): Just what I was looking for!
Well executed product.  this replaced a similar looking vent hood with just louvers (flaps) - no access door.
Cleaning my dryer vent was always trouble because taking the louvers out of the old one nearly always broke a louver - because they became brittle after a few years. (the vent is in a place where direct sunlight does not reach it.)

I'm hopeful this will hold up well.

Other thoughts. As I had to do with the non-access door vent before it - I used a hacksaw to cut off the flange on the hood - would not fit in the existing hole. Then just caulked the face to the stucco.
