Product review (5 stars): And our food stinks (well actually it's quite good just stinks to cook)
Very high-quality hood.  Basically a PRO-LINE for about 1/2 the price.  I have had it for 5 mos now.  We're a packed Asian family, so we cook ALL the time and 3 times a day.  And our food stinks (well actually it's quite good just stinks to cook).  I have used and replaced the venthood in our old home w/ a big box store product (their top of the line) and it was not nearly as effective as this hood.

The 900 CFM allows me to use a WOK inside the house and not smell like dinner for the next couple of weeks.  You do have to crack a window open given the high air volume being removed from the inside of the house (else you can backdraft your furnace's CO2... not good).  Haven't gotten around to installing a makeup air system yet.

Install was fairly easy for me, but I have all the tools and a lot of experience doing house repairs.
1. Small jack to lift the thing up and hold it in place
2. 12 inch extension w/ a power drill w/ LED lights to mount it
3. 3/4 plywood scraps (3/4 x 2in x 10in) to level out the bottom of the cabinet

DO NOT use duct reducers.  Basically limiting the effectiveness of the unit and not getting the max 900 CFM (which is why you would buy this in the first place).  Relatively quieter than most other vents.  Very easy to clean and keep clean (I use my power washer to clean the fans and grills).
