Product review (4 stars): Totally decent hood...for the price
What you see is what you get. Nothing fancy here, but a decent functional range hood for a very reasonable price. The unit comes almost fully assembled, you just hang the fan/glass unit on two screws, then slide the chimney trim into place. You will have to mount two screws at 9 3/4" on center in order to hang the fan unit, and set two anchors in the ceiling or the top of the wall to hang the chimney part. Hopefully you can hit a stud with the fan unit screws...I wouldnt trust this thing hanging off drywall anchors, its pretty heavy.
 Some of the cost savings are apparent: it includes a corrugated PLASTIC duct, which sets off all kinds of alarm bells in the fire safety compartment of my brain. In the manual it say "use only rigid steel duct"...so why they include the plastic one is beyond me.
  The outlet is a 6 inch duct...so don't make my mistake and install the (in my mind) typical 8 inch duct in the wall. The fan duct exits flush to the back wall of the unit...so hopefully your pipe is flush to the wall also. If not you will have to take a jog to hit the duct. Noise is a B-minus, venting power a B-plus.
All in all, pretty darn good, given that you can spend 4 times as much for a very similar unit from GE, Broan, Zephyr, etc.
