Product review (5 stars): Great performance, amazing value and looks nice!
This unit works great.  Yes, it is a bit loud on the highest speed, but you should expect that.  I find 3-400 CFM works for most applications and the sound level is more than reasonable.  It is also a great looking appliance.  I add that second, because most of the vent hood reviews I read while shopping said nothing about performance.  Yes, you want something attractive if it's going to be a prominent part of your room (and on an island, it will be), but I do not want food odors and smoke throughout the house, and I needed a unit that would rival the commercial unit I had before we knocked a wall out.  This does.  Plus, it is easy to clean, and don't under-estimate the value of controls on both sides.  Our island is huge, and to be able to turn off the fan or lights from the seating side is an unexpected bonus.  ONE CAVEAT - remove all of the tape  from the halogen lights before you turn them on!  The tape will permanently burn onto the bulb.  We're hoping we can ultimately replace them with LEDs.
