Product review (4 stars): It's SUPER quiet on the low setting which is enough power ...
This hood is available under a few brand names from a few different places.  I purchased mine elsewhere yet it is identical to this one.  It's SUPER quiet on the low setting which is enough power for average cooking, even on medium it is on the quiet site.  On high it is definitely audible but on par with what some hoods sound like on low.  This is far quieter than the $1000 Ikea units or the high end hoods costing a couple grand.

Install was relatively straight forward and the unit is actually very well engineered inside.

I have two gripes with the unit; however.  I installed it in a kitchen with a 8ft ceiling.  I had to cut a large chuck of the internal frame to get 29in of clearance above my range.  I ran out of factory holes then to attach it to the frame piece which attaches to the ceiling; I had to drill my own.  The chimney covers worked just fine, on the other hand.

Finally, the operation is a little odd as you have to press the clock button to power on the hood to then use the + and - symbols to turn the fan up and down.  If you hold the clock for just a little too long it will go into time set mode.  It's not the end of the world but that part is not it's strength.

All in all, this is a very good hood for the price and if you shop around you can get it for quite a bargain.
