Well made but bathroom extractor on high speed not capable of opening shutters
Well made but extractor fan not capable of opening shutters in vertical position. Even when extractor adjusted to high speed.

Working well so far
It's only been installed for a couple of weeks but seems to be working well. It replaces a plastic flap that was hinged on one side and always banged noisily when there were high winds outside. This one has passed that test and seems to have reduced the backdrafts we were getting.

Needs a good fan to work
My extractor does not produce enough pressure to open the flaps. I managed to bend the spring enough to get the flaps to open. Pity as it is well made.

Worked good for our hood fan
Hooked up inline with our hood fan above our stove, prevented back draft of cold air in the winter season. Easy install
