Works for it's purpose
We live in a very rural, windy area. Husband installed a vent for the microwave fan above our stove to vent outside. Any kind of wind had the vent making so much noise throughout the day Abe night. We finally got fed up with it and purchased this... it was extremely easy for him to install and sealed great! We no longer hear the extremely loud, annoying flapping and it has stopped so much backdraft. The fan ventilation system is even quieter than it was before! We've had it installed for over a month now with some pretty nasty storms and seems durable!

Very good
It's very important to prevent air escapes from your house.

Just.works.period.
Wow, what a difference this simple change made! When I first removed the dryer exhaust pipe I could feel cold air pouring in from the outside. Slipped this in and the airflow was immediately cut by 95%. My laundry room is now noticeably warmer. I checked after a month and no lint build up. The only think that irks me is that I didn't put this in years ago!

Little plastic flaps on vent fans and on roof vent are NOT enough
Little plastic flaps on vent fans and on roof vent are NOT enough to stop wind from sucking air out of your house.When a medium wind goes over my house, I can feel and hear the wind lifting the plastic / thin metal flap andsucking the air out of the room.The reason I know this is because these are the fans that were installed before I discovered the Backdraft Damper Shutter. Those fans "leak" (/Back draft) alot of air.Now when I install any fan ( 4", 6" vent), I install one of these Backdraft Damper Shutter and it works great.

Good damper, works well, allows dryer to still blow out air.
Nice damper for dryer, keeping the cold air out which helps the overall temps in the room.

Easy install with foil tape.
Nice damper. Works great for my dryer exhaust system. Hoping to keep some cold air out of my dryer vent exhaust. Seems to help a bit. Def will keep critters out, not that I ever had a problem before… but nice in the Winter time to reduce cold air infiltration.

No more cold air
I felt cold air under the microwave when it was 30° out. Slipped this unit in and at even zero degree outside temperature I feel absolutely no cold air.

Nice piece
I put this damper in a horizontal run of 6" duct for a range hood. It fits right inside of standard 6" metal duct. I taped it place with aluminum tape and all is good. Because it's in a horizontal duct, it just needs to be oriented with the pivot shaft vertical, so the flaps will swing properly. It opened just fine with the range hood on low, and closed positively against the gasket that surrounds the opening when the fan is off.
