I chose this hood for my new house with an outside vent. The lights are bright as I expected. However, the venting is disappointing. Although the house's outside vent flap opens when the hood is on - showing airflow to the outside- a considerable amount of air is blown back into the kitchen as well. The airflow through the hood's top vents adds considerable undesirable noise to its operation. Also, on the lowest setting there is a distinct undesirable hum.
