Product review (3 stars): Possibly quite a bargain, but inspect it carefully.
The description of the item I purchased was "Used - Very Good - Item has no cosmetic scratches or blemishes. Item has no cracks or dents. Item will come in original packaging. Packaging will be damaged."  Unfortunately, since the packaging was not damaged, I did not closely inspect the item until it was time for installation in my kitchen.  As it turns out, there were a host of problems including loose parts within the hood (the power transformer, was supposed to be held in place by two screw/nut combos, and was just floating loose), and a big corner dent on the back left corner that I was able to flatten sufficiently to install the item.

The fan is wonderful and quite quiet for the amount of air it moves.  Installation was pretty straightforward, but the instructions are not that helpful.  For instance, the baffles remove by sliding the little knobs backward and the front of the baffle then drops down.  I was fooled because there is a little knob at the front that looks like it unscrews, and there is a handle at the back that looks like something you would pull on.  The manual also describes a "grease cup", but it's a rectangular piece of clear plastic that would be overflowing if you stacked five quarters in it - not "cup" shaped and certainly doesn't look like it will hold much grease.

Bottom line - if you buy one of these, inspect it very carefully when you receive it.  There was no indication from the box / packaging that this had pretty obviously been dropped on one corner.  I know I learned my lesson.  If you get a good'un, you will have scored a bargain.
