Good vent covers for the price.
These vents are a great fit for the existing cut out space for vents under the house. They are a good price and have a cover that easily covers when needed and they were easy to install. They seem to be good quality, they are working great so far.

Great product
These look great and are easy to install a great alternative to the metal crawlspace vents and provided a very clean look when installed with vinyl siding.

Nice it installs over the existing vent.
The vent looks nice and was not very hard to install. Drilling in the brick and mortar was hardest part. It remains to be seen how long they last and I question how long the vent cover stays attached. The attachment part didn’t look like it would keep it on. A big wind might blow it off. Time will tell.

Good invention but very cheap fabricated or a bad batch sold by 3rd party seller?!
I am very disappointed because the invention of this product and maybe also the intention to create a good product is not in question.But the product was very cheap fabricated or is a bad batch that is being sold by a 3rd party seller?!The louver should be permanent fixed but was totally loose on my first delivery and on the second some pins that should hold the louver fixed in place looked like they were clued to the frame manually.The snapon cover fell off very easily on both of my deliveries. Think about it, when the cover will fall off easy, at the same time the louver is loose and will fall off too and on top you do not have installed anything behind it everything what fits in to 16"x8" will enter your crawl space!

Seals the crawlspace in winter
Easy to install . I like the cover for the vent. It seals better than the metal ones.

OK but cover can come off and not made consistent
I purchased 3 of these for my basement workshop. Expensive for what you are getting but nice ABS plastic. The cover on 2 of them fits into place but not snugly. There are 2 buttons on the cover that push into holes on the frame that barely hold them on. In strong winds or rain I can see them coming off. The 3rd identical one I installed, the cover would not stay on. It seems if the installation causes the frame to even bend slightly, the cover has problems popping in. Not sure if I can use my heat gun to melt the buttons to push in more to snap better into place. Two big non-detachable plastic screws would have been better. In any case the way it is designed for the cover to snap in is not robust and I would expect a better design for this price. I now have to figure out a way to keep it snug and not fall out yet be able to be removable. A good product but has issues.

New crawl space vent
Needed a replacement vent. This one was reasonably priced. Very easy installation and has held up well.
