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

Perfect size. The quality is mediocre. I had to glue in the screen. The weight is very light, air flow is sufficient. Nice little product. Great value!

I didn’t want to spend a lot of money so I chose this vent for its price and rating. Plastic was good quality and I think is a great value

I purchased this to prevent my cat from escaping. It worked! :)

Looks good and installed well. Has a pretty fine bug screen. Which is needed.A little concerned that over time household dust and moisture will clog it up (especially if anyone is using alot of hair spray). Bug screen installs from the inside so to clean, you'd have to remove the whole thing, unhook duct, and access it that way. I suppose it's possible to dislodge screen and pull it out the louvers but it will be a challenge to reinstall after cleaning. A design to allow screen removal would be ideal. That is the only reason I rated it 4 stars .

Sturdy and well fitting. Very smooth.

Filled the bill perfectly

Great product

I feel that it is too restrictive and is making the exhaust fan work too hard
