Bang for your buck!
I bought two different products due to quantities needed and the availability. Of the two, this one was a bit more money, but totally worth it. The quality was just so much more superior than the other. Installation is a little time consuming when installing 12 of these, but each one was about 5-7 minutes to install. Automatic part works well. I have 5 of these under my deck, so to get to them to change them would be a pain. Automatic are the way to go.

Great replacements for an older foundation!
These are amazing! I replaced what looked like the original vents that were put in 60 years ago. None of them had the same size opening in the foundation but we were able to replace them all with a little creativity. Installation would have been easy peasy if not for the foundation inconsistencies. It turned off cold this week and they all closed automatically, so now I won't have to go out with the hammer next spring and beat them open. I definitely recommend these.

Great appeal and easy to install.
These vents have a great appeal as well as easy installation. I replaced the original vent on my brick home with theses new ones. The price is affordable.

Easy to install but automatic closure doesn’t work
Installation was easy and fit well in our 40 year old home. The problem is when the temperature dropped about half of then did not automatically close. There is no way to manually close them.

Automatic don't work
I don't know why they do this, except for marketing. The bimetal spring that moves the louvers is not strong enough, and this thing does NOT close even at 30 degrees. I'd MUCH rather get a manual vent, but NOBODY SELLS THEM!!! Sigh.

Install screws didn't work, overall quality is good
The installation screws are located too close to the outer edge of the cement blocks and with a 1/4" waterproofing coating on the walls, the screws cannot bite into the block, instead they chip off the coating. So we ended up using adhesive caulk to glue them in place. Other than that issue, the vents are of decent quality and no evidence of defects.

Really automatic Vent...
The product does what it says, but Screw Adjustments on Automatic Vent are hard to get started. Fit is made for concrete foundation but can be adapted to cement plank siding .

Looks good but don’t function as designed.
Device does not close as designed. Even at 7 degrees out it is wide open. There is no manual override so only option is to replace it at this point. I have another one that is functional so seems to be inconsistent quality control. Other than functionality (the most important part) it seems to be a reasonably good product. Shame it don't work.
