It's so discouraging to have to contend with poor workmanship. I researched these things, read the reviews, did my homework, and then ordered an expensive name-brand part. So when this vent arrived today and I opened the box, I was crushed to see that the fit of the flap, which keeps the cold air out of the house, is so bad. The rubber gasket is supposed to be glued to the body of the vent assembly to fit tightly up against the moving flap, preventing airflow when the vent is closed. The rubber gasket on the unit I received was a full half inch misaligned, keeping the flap open all the time. I need to install the vent next week to keep my project on schedule, so I'll try to remove and re-glue the gasket in its proper location. But why do I have to do that? I paid a premium price for a junky product and I'm mad. I'll try to upload some photos.

Broan used to be about quality, not so much anymore. The seals on both sides of the flap were way off! keeping the flap open about 3/4 of an inch. If you don't mind cold air blowing in or bugs getting through then it's worth it

Horrible quality, the cap was not lined up with the foam strips, so it did not seal out the cold air. This is the same problem other reviews had. Do not buy this. A much better alternative is the one below, I got it and loved it.

those in home depot are made with super thin aluminum sheets, and they are so flimsy that if you
wave them in the air, they flap around and make sound from the warping of the metal.

This one is made with aluminum sheet of about 0.7-0.8 mm, very strong, no flexing. The seal between
the base plate and the duct is also very tight. Compared to this, the home depot ones have large chasms between the fits, and they had to put a lot of rubber caulking over the seams! imagine over time that the caulking would give out, and water would get in.

Bought this item to vent out an existing Broan range hood. The wall cap looks solid enough and has a well sealed anti backdraft trap.

This vent is not flimsy. It should last. It is made in the USA :)...I would have rated it higher but the way it is made it has a spring that closes the damper. They put a gasket material down both sides but nothing across the bottom or top. So air can infiltrate the house... I am thinking that the pipe that will be installed before you get to the wall cap has a damper in it. So hopefully that will keep out unwanted air..... I dont believe I would recomend this unless you are installing another piece with a damper or maybe adding some weather stripping to the wall cap to seal out unwanted air...

I like the built in feature of bird nest and the spring damper. However the pipe connection is a little tricky as it is short. I drilled holes through to connect it up with the 6" pipe before inserting whole thing into the wall opening. Just hope the spring damper is not too strong that requires a large CFM hood. I can hear the damper bouncing when hood is on and off, so air are moved out of it.

Recently purchased this wall cap for a new home I am constructing for a customer. The vent assembly itself is fine. The wire mesh screen to keep out birds is sufficient but will not keep insects out. The main problem though is the damper is flimsy and simply does not seal well at all. Out of the box the damper was not sitting flat against the foam rubber seal provided around the vent opening. Since the damper is simply a sheet metal flap designed to lay against this rubber with a small spring at the top pulling it closed the seal will never be airtight. I could not get the damper to lie flat even with some minor bending/twisting of the sheet metal. Will return for a refund and keep looking for a wall cap with a damper that actually seals.
