Hon&Guan Soffit Vents 4 Inch, Round Exhaust Air Vent Cover with Built-in Fly Screen for Bathroom Kithchen Office Home, White

Nice product. Fit perfect. No tools needed.

Worked like a charm. SImple to install and snapped in. The only adjustment was the insect screen was loose and had to get that in tight. Make sure you drill a 4.25" hole

Easy installation and helps draw cooler air in to help keep the back of my built in refrigerator cool. Nice strong plastic used.

I used this for a bath exhaust fan that’s mounted in the attic. Nice discreet look and worked well.

Made for mounting on surface that is no thicker than drywall. I used it in 7.5" concrete wall so I made a 4 inch hole and lined it with 4" PVC pipe. Vent wings allow it to stay in place and caulking around edges secured it to weather tightness. Airflow was adequate. Not installed long enough to speak on how well it stands up to the elements. Replacing will be a quick task though. Material seems robust enough to last for several years.

Very convenient

Fits perfectly in the piping for my dryer vent. Quality feels durable and doesnt have any type of smell. It is easy to put on and just forget about it. Provides great airflow and is a great replacement to what I had before.

Awesome! Great fit and I like the side tabs that keep the vent in place. Still use a little caulk to keep the vent on the black housing because it will fall off. For the money it’s a solid product.

Worked great! Even installed in colder temperatures and the plastic isn’t brittle

I ordered the 4 inch vent to replace a broken outdoor vent that leads into my cellar. This is decently priced, looks clean, and does the job. I like that it has the 3 tabs that help hold it in place of the concrete opening. The rodent/bug grate is a separate piece and I'm not sure why. Maybe to allow if anyone anticipates putting cables through the opening slots? I've had utility companies do this in my last house. I used some gelled superglue to keep it from coming off as it pops off if pressure is applied from the outside, inwards.

Worked as expected

Correspond aux indications. Installation facile sur un mur de gypse.

Works great as a dryer vent cover and birds and bugs aren't able to get in the vent for warmth
