Product review (3 stars): Good hood but extremely painful installation!!!
I did very carful comparison of modern kitchen hoods that is 36" wide, has a powerful motor, and has a thick stainless housing. I gambled on this one and were really happy when I received it. It was more beautiful than what appears in the photos and I was thinking to give it a 5 stars.

Then here came the ugly side of poor documentation and bad design on Instalation. I am a very handy DIY home owner that I installed a 20 feet craft mate kitchen two decades ago and remodeled two bathrooms. But this one took me more than 12 hours to install. There is no documentation on how to put the air deverter on the hood. It is not straightforward because it has a rubber gasket, a bracket to hold the lower chimney panel, and the deverter all had to be screwed together using the same screws. Then the deverter corner protruded a little that prevented the lower chimney panel from sliding all the way in to meet the dry wall. So I have to use a hammer to dull it. When I turned on the blower to speed 4 the whole hood starts to resonant sounding like the motor is griding on something and the whole hood is about to explode. It ended up the diverted flaps resonanting at wind speed 4. So I have to stick a piece of weather strip to damp it down. I have a 10 foot ceiling. So have to pay more than 100 dollars to buy a piece of upper chimney. The chimney is slippery and heavy, and it has a very small mounting screws hole that position very close to the ceiling and guest what... it is not slotted. So I have to stand on a tall ladder, trying every means to keep the upper chimney from sliding down, and at the same time trying to align the tiny screw holes on the chimney and the bracket in an aweful head position because they are near the top of the ceiling. I kept dropping the tiny screws and had my wife did a search and rescue of the screws. After two hours of ternaciois effort, micracal happened. I managed screwed in two of the four screws. I gave up on the other two. Now I pray nothing should ever happen to the hood. It will be a nightmare if I have to do this again.

Extreme air hood main design seems good. It just have so many loose ends that they need to go learn from IKEA, or have their dumb designer or sales go install on a10 foot ceiling 10 times. The dumb guy will eventually wise up and improve on it.
