Product review (5 stars): We love it......but wish it was not as loud
I did my research for a range hood while my house was being built. We cook food that uses a lot of onion, garlic and other spices which stay around long after you are done cooking. After reading a ton of review everywhere I decided to get this one. Luckily our gas range is on an external wall so I was able to vent it to outside using a 8" 90 degree bend. The screws that came along to hold it to the bottom of cabinet didn't seem enough to hold it so I decided to use the bolts they use for hanging microwaves, much safer. Putting the 90 degree bend was a pain because I wanted as short of duct work as I can but the builder put the wall louver on the outside a couple inches higher. Since there is on 2" extension for 8" duct work I had to use a 8" extension and metal snipes.

It is a little louder than what I was hoping but during my research I couldn't find one anything that made less noise. All the features work including the auto on if the heat gets too high. Just to make it clear I have only seen the 2nd fan turn on by itself when I had only one on. It works great though in clearing the smoke/smell right out but I have noticed that if I keep all windows and doors closed it doesn't work as good. I guess it is expected because the air needs to come from somewhere to go out, we generally open our dining room window a little bit when we cook. Cleaning it is easy but messy. All the oily smoke that gets cleared out also drops the oil on the pan and it becomes a thick sticky stuff that needs to be cleaned.

The way I installed it, the back is completely against the wall which means the front of the hood is not in line with the front of the gas range(look at the product picture). What I do notice is that sometimes some of the smoke manages to escape from the front. If I were to install it again I would move it about 6" forward because that much space towards the back or gas range is not for cooking anyways.
