Product review (4 stars): Think of it as a starter kit
Think of this hood as a starter kit and you will have the proper mindset going in.  It's best feature is the price.  (It was $299 when I bought it November 2014).  I'm not sure where it's manufactured but it's a good bet where ever it is, they don't speak, write or understand English - the directions are that 'good'.  The seller I'm guessing is the US distributor - they sell the stuff - period.  There is no tech support to speak of, and if there is, they don't let him talk on the phone.

If you are mechanically intuitive, persistent and like a rock bottom price - then jump on this.  You can't touch an American made product similar to this for any less than 2 or 3 times the cost.

When I installed it I found that the fan produced 82 Db and was moving about 130 CFM of air and the lights reminded me of those irritating blue headlamps you see on the road. 82 Db is pretty loud, 130 CFM was disappointing and the lights were unacceptable.

I removed the fan that it came with and installed an inline fan up in the attic.  I added a speed control at the hood and an additional wire run for the control.  The new fan is barely audible, and moves over 350 CFM - perfect.  The lights I had to replace with a warm light LED, 1 watt and re-engineer how they fit into the hood.

I ended up putting another $150 into the job but it looks like a million bucks.
