Product review (2 stars): OK but overal attention to detail in the units' construction and quality control could be improved.
Once installed, its a good unit. When we received it, the packaging was fine but the unit arrived with some of the metal trim corners bent, a plastic electrical connection box (inside the unit) was broken and a bolt securing the fan motors was unattached and rattling within the unit.  Since our installer was on site and ready to go, we corrected the issues but shouldn't have had to. It's loud but really moves the air.  It does have two motors so maybe the noise should be expected. Overall it's fine and looks and works fine. We were dissatisfied with the quality of the unit when taking into consideration it's cost.
