Product review (3 stars): The Good, the Bad, and the Ugly.
The good is that the looks of this hood for the price is just out of this world. The bad is that the information about this hood is near non-existant and the quality is somewhat cheap. The ugly is that the unit I received has a small dent in it near the exhaust vent at the top. You have to look for it now that it is mounted, but it shows careless handling nonetheless. It also came with a cheap candelabra incandescent bulb, not the LED or halogen that some other reviewers implied.

This hood has THREE installation modes. 1) ducted up, 2) ducted behind and 3) DUCTLESS! Yes, this hood can be installed without a duct and comes with carbon filters so that the stove fumes blown back into the kitchen are filtered. The fact that this hood could be installed ductless was very vague from the description and one buyer even stated that it was only ducted. If you look at the picture I posed you will see a small lever on the fan plenum that points to a house graphic with an arrow pointing in. That's the ductless mode. When the fan is on it draws air up through the hood and out slotted vents at the top of the hood. In fact, the vented air blows out almost vertical towards the ceiling.

So, great looks and clever functionality. Cheap construction, but once installed that is something of a non-issue.
