Top bit of kit
Brilliant, sorted out the air coming into the property instantly! Felt warmer straight away, and looks very tidy and good quality. FOr the price of it as well, cant fault it at all.

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

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

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

Bisher alles ok. Klappe funktioniert wie beschrieben. Einbau war einfach. Gutes Produkt. Sehr zu empfehlen.

This is not the first AC Infinity product I've bought. I already had an AC Infinity humidity sensing fan with a quality level that impressed me, so I decided this was the best brand when I needed a back draft baffle for my 8 inch kitchen fan exhaust. Similar build quality. You'd think this was a turbine engine part.
