Product review (4 stars): VERY quiet range hood!
This is really a quiet range  hood. I looked for a low sone ranking....the motor is indeed quiet, and I like the variable speeds. On Quiet setting, it is really a nice, quiet hum. My only wish for improvement would be with the lighting. The lights are at the front of unit. My back burners on not lighted as much as I would like, so I usually turn on my undercounted lighting.
