Product review (3 stars): Poor construction
When I first plugged in this hood it started buzzing incessantly even if nothing was turned on. By banging on various bit on the inside of the hood I was able to make it stop, start, change tone, whatever - because the interior pieces are made of very thin gage, tinny sheet metal. I finally found the problem - a small (and cheap) transformer's core was loose in its frame. I crimped it down with pliers and the noise stopped.

Now that the buzzing stopped I tried out the hood. That's when I noted that even though I set it up for outside venting, some air was still coming out the interior discharge vents. The blockoff plates they supply don't seal as well as they should, but a judicious application of duct tape fixed most of the problem.

Other than that the hood seems OK. These issues would certainly be acceptable on a $60 hood... but THIS thing was almost $400! WAAAAAAYYYYY overpriced for how it is built.
