Solid, heavy, well made.
Very solid unit. Walls are easily 2-3x thicker than the cheap ebay one I had before. Great design and quality.

Performs well. Nicely made product at a fair price!
The AC Infinity products I’ve been getting all seen to be superior quality pieces (fan, collars, dampers). Couldn’t be happier. Shutters open easily but close solidly when there’s no air flow. Thank you a great product at a fair price!

Nicht mal eine Anschlagsdämpfung
Das größte Außenmaß ist 206mm nicht 200mm. Die Klappen schlagen hart an und sind ungedämpft. Schöne Optik, aber mehr sicher nicht

Highly recommend Great Quality item
This company puts out "quality" items Something we dont see to often anymore. This item works great when exhaust fan turns on and closes nicely when fan is off. I like the rubber gasket Keeps cold air from coming back into house BigBox stores carry similar item BUT not as well made and more money Highly recommend
