Product review (5 stars): Works very well
I ordered this using Amazon Prime. It came on time with free shipping, No damage, with all parts, I plugged it in and tested it out before installation. I used a car jack and with my wife's help, we fit it fine to the microwave oven space. First, we were concern about the high spacing, because from the recommendation it should be 26" from the counter surface, we have only 22", but by watching other customer's YouTube with the similar height and it is nice to keep the overhead cabinet, also from efficiency, the lower to the cooktop, the better; we decided to buy this hood. I had to run a 7 in a duct to the ceiling and 90 degrees from the top cabinet 12' across the kitchen ceiling to the outside wall. so duct work was the hardest thing in the process of installation. It took me a day to prepare and ready when the unit arrived. My other concern was 7 in duct instead of 8 in, but I saw other reviewers also using 7 in duct. It was easier because I still can keep the recessed light in the kitchen ceiling which is happened to be in the same slot with the duct.  The beams supporting the second floor has 16 in spacing and 8 in height, so running 7 in duct was the right choice, because there are electrical wirings across the slot. I measured the noise test with an app from my iPhone standing in front of the hood. The results showed 60 dB to 69dB for speed 1 to 4. So it is in line with seller's ad. I ordered a stainless steel kick plate of 30" x 12" to cover the wall in between the hood and the cooktop. It fits nicely; purchase from Amazon as well.
We cooked Pho (Vietnamese noodle, which creates a strong smell of the spices, I like to eat, but hate the smell in the house
We tested it out, with level 4 we don't smell it except in the kitchen.
So overall we are happy with the product. Hope its lasted (please help to rotate the pictures, I don't know how.)
