Made of a durable hard plastic. Looks very clean and installed easily.

The frame is tough and well-made, and the shutters are even linked together (they close by gravity, no spring). I ended up not using it because it's too big, at 9 inches square. It could have been 2 smaller both ways pretty easily; but if you have enough space, it seems great. It has no bug/rodent screen, but there's enough room to screw or glue in your own....

Excellent exhaust vent, very durable. Great job!

Easy to install

Nice Vent, I have a little issue, My fan motor isn't strong enough to lift the shutters up much. But still a well made unit. I've ordered a stronger fan motor.

I bought this to put on my garage for an exhaust vent. It is very sturdy and good quality and you can't beat the price. It was relatively easy for my boyfriend to install as well and we are very happy with the product.

I was pleasantly surprised when I opened the package to see this vent. It is sturdy and constructed to last a long time. Louvers all open and close together as they are linked to each other. The paint job was a quality finish. Each louver has a rubber bumper so when they open and close they won't make a lot of noise. The only thing I wished for that this doesn't have is a bug screen. There is space behind the louvers to add one, so I'll do that myself. I haven't installed this yet, but it should be a breeze. I look forward to many years of service from this vent - I'm glad I bought it.

This seems very well built and sturdy, however it seems like the fins are a bit to heave to go along with the 6 AC Infinity fan that I have on my Glowforge. A small drop of oil on the hinges seemed to help, but even on full power they only open 1/4. I can notice a definate difference in airflow if I manually open them all the way, however this defeats the purpose of having them close automatically.I like the sturdy construction of the main body, however I wish the vent fins were ligher so they would open easier like the 4 vent I had on before.

Good quality build. Didn't work out for what I needed it for but let me with very good impressions

Shutter was very well made and works very well.

I like that the vent is sturdy. It was exactly what I was looking for. It's made out of good material should last a long time
