Excellent replacement for a precision product that has become dry rotten after 10 years. Yes, this product is brown as requested, contrary to Revain's description which says it is white.

I used this to replace the ones for the bathroom exhaust fan through the brick wall and outside. The old one was the same size but without blinds. The new vent feels solid and should last for many years.

Installation was average as it depends on where the vent was originally installed. The materials gave a little more than I wanted, but this device survived the tough months we've had. Blinds are easy to open and close.

This was exactly what I was looking for to replace an old block that was falling apart. The build quality is excellent, the color matches the house perfectly. This is a very strong block that easily withstands being pushed and adjusted to fit an old house.

When my original aluminum dryer fan got damaged after 15 years I wanted something that would blend in with my brown house and at Easter you can see if it's stuck if it's open or not. That works great. The multi-louvered fan is easy to install and easy to see that it works and closes completely.

Bought a pair of these to replace the old ones. The only thing I would like is for the holes to be a bit bigger as the drill bits tend to wander around and if you get it a little wrong you will need to take the blinds out and sand them down a bit to keep them from sticking and opening . Since they are on the south side of my house I will be buying two more in a few years and filling and fixing the "off-center" anchor hole.
