Unit looks good,  but it's definitely not as powerful as some of the review claims,  also the motor vibrates when in low and medium settings,  it's really annoying.  my 7 year old cheap chinese range hood was rated much lower CFM, but it runs much smoother, exhaust more .  Do yourself a favor,  spend more and get a better unit,  it's worth it since it will last you forever.  stay away from this junk
