We just got it installed today. The handy-man who installed it was very impressed with it and pointed at couple of nice features (like the dual fan and quality). We haven't used it much yet but the exhaust pipe was getting pretty good flow out of it. It was almost like a leaf blower. I'm hopeful it will do the job as we cook a lot.
I bought the 30" hood last week and just finished installing the unit couple days ago. I like the appearance, high quality, and powerful suction. It is fantastic product with beautiful lights under hood. The lights are bright but easy on the eyes and I can see what I'm cooking. The digital display is perfect and super easy to use. I used to have the microwave hood vent, and this is such a big upgrade. The suction is much more powerful. Installation is fairly easy. Hopefully it will last a long time. Highly recommended.
