Easy to install

I decided to use the dryer vent to run my portable ac exhaust and it was backing into the dryer. This was easy to install and it worked perfectly and now I can keep my room cool without having to block my already tiny window that’s a hopper style

Does what it says it will do.

Was getting moisture in my dryer from other units in building. Solved the problem completely. Installtion was easy.

Great quality. If your stove hood/microwave baffle is junk swap for this.

I had a high volume of backdraft coming out of my over the range microwave making the kitchen 12 degrees colder than the rest of the house when it gets cold. I played with the baffle that came with the microwave, which involves taking down the microwave each time, bouncing between allowing it to work but really not stopping any backdraft to it getting stuck preventing any stove venting getting through. If I had bought this 17 dollar (6in black) item before this last cold spell I would have saved hundreds of dollars on heating. Everything is quality with this. For such thin (lighter is better) sheet metal the vanes are perfectly flat and square making full contact with the generous gasket keeping all air out of the house. The lowest setting on the vent fully opens the vanes. Even the paint job, where only a 1/4" section can be seen when installed, looks high quality. Easy to install just pop off the vent cap outside, drop this in to the vent pipe (I then duct taped it because I didn't by a clamp) then tighten the vent cap back on to the other half of this.

Great for Bathroom Exhaust Fans with lousy factory dampers

Perfect for what I needed; my bathroom exhaust fans, although they have their own dampers, leak outside air into the house as if the vent was wide open. This was causing some major condensation issues so I decided to try these dampers. So far, I have noticed a huge difference with absolutely no outside air leaking into the fans. The quality is pretty good for the purpose it serves; however, one of the springs on one damper was much looser than the other damper so I did shave a star off for obvious lack of quality control. Overall, this seems to work really well for me and I would recommend these dampers for those in the same situation as me.

Quiet Quality

Strong. It opens easily with very slight pressure. Closes quickly and seals up great. It actually slides inside the pipe snugly, which is great, because your pipe length does not change. Very impressed. It is also whisper quiet when it opens or closes.

Not a very strong close spring

If this vent is installed with the air flow going down, the springs will be challenged to close the vent due to the weight of the fins. Likewise if the orientation is horizontal with the hinge flap horizontal, the spring will struggle. The construction and fit is solid with a good seal when closed. Will do the job keeping in mind these conditions.
