Product review (2 stars): Very load unit, for this much money I would expect a quiet unit not an airplane engine!
The hood is nice looking and I like the LED's.  But the non flexible install requirements were a bit of a pain.  That said, once it was in, I discovered this thing sounds like an airplane in the kitchen when it is on medium or high... that defeats the purpose!  Very load 73-75 DB...  By comparison, my dishwasher is 43DB...
