A carpenter had installed these vents, but some of them fell out of the holes in the soffits. There are no teeth or knurls or other projections on the sides of these vents to hold them in place once they're installed. Some of them were lost, so I had to replace them. I slathered the sides of the replacements with exterior silicone glue before installing them. (The package doesn't include installation instructions.)
Furthermore, there's no screen or mesh behind the slots in the vents to prevent small insects -- say, termites or carpenter ants -- from entering an attic through the slots in these vents. I cut circles of screen and glued them inside the vents, behind the slots.

This product should include some type of screen inside to prevent insects and small animals from
entering between the louvers.
I will now need to juryrig some sort of screen before using the vents.

Rated 3.0 out of 5.0 by Stovie great venting application
these worked great for venting. i would say that there was one small issue. if you use a 3 inch hole saw the fit will not be as snug as it should be. Needed to add a little caulk to keep it secure.

I just installed these vents to my roof porch, and they are really nice. Another reviewer commented these don't stay in place, which is true in my case. However, a bead of exterior caulking resolved this problem.
