6'' Soffit Vent Exhaust Vent, 6 Inch Round Air Vent Dryer Vent Soffit with Built-in a Fly Screen for Bathroom Office Home(150mm）

These are pretty sturdy for being a plastic-type material, and they work as expected.

Used for exhaust fan vent works perfectly

It’s very Easy to install. Ít is working very well/(perfect) Price is very lower for what it does that well, 👍👍👍👍

I really like this design concept. The white screen part fits very snugly into the black part with friction only, which seems to work well - though I'd probably have thrown a screw into the white flange to be sure it doesn't fall out in the winter. The black body has wings that you squeeze with your hands when you put this up into the hole, and then expand back out to hold it in place, works pretty well. The black body is not 3 inches in diameter, more like 2-3/4 inches. This wasn't an issue for us because we had flex tubing, if you're using rigid tubing this might be a problem. Finally, we didn't end up using the white part because it restricted the air flow too much. The screen is just too fine. It cut about half the airflow. I ended up using the old cap from the vent we were replacing, modifying it to fit the black part. It wasn't perfect but worked much better. The old vent cap used screen door material, which let a lot more air past. I'm not saying this is bad, or that you will need to do this. And, maybe you want a finer screen to keep out certain insects. For us, airflow was more important. I'm giving 4 stars because the diameter isn't what is stated and the screen is too restrictive, but still like the overall concept.

Good product, fit perfectly and work on my application just as it should have

Good quality, easy to install

This is good stuff, it was very precise in dimension, and strong not brittle plastic.

Easy to install and durable. I added screws to help hold it in place. Hold in place very well on its own. Good price
