Product review (5 stars): Beautiful and Functional
Ordering ordeal, but worth it in the end.  In the process of a major remodel I ordered this unit from Amazon, I should have received three boxes, but only got one with the remote blower.  I sent it back and got a refund.  I ordered again from the rangehood store, and got two boxes.  Once the contractor opened them and saw that there was no chimney kit included, I called them and had it sent, 12 days later it arrived.  The chimney kit was for a 8-9 foot ceiling.  The two pieces telescope together, they are about 16 inches tall each.  We had to cut one piece down to get it all to go together and look good, but that is pretty normal.  I used an abrasive blade ($5.00) in my table saw, took about 30 minutes including changing blades and sanding the edges smooth.  I would not suggest this for a novice handyman.  We had an electrician run a dedicated circuit, a roofer for the vent and the AC tech ran hard ducting between the hood/blower/roof vent.  We did not use the included flex duct.

Note that we used just one set (the short ones) of the angle brackets (4 short and 4 long, can be used together if needed) to hang the hood, with an 8 foot ceiling and a 35.5 inch counter height we had 31.5 inches clearance to the hood (67 inches from the floor to the bottom of the unit)

Also note that we used a 42 inch unit over a 36 inch rangetop.

Now the good stuff.
1.  It looks great.  All surfaces are smooth even finished stainless steel.  No weird seams, no plastic, no cheap junky bits.  The inside looks like a commercial kitchen hood.  Even the parts you'll probably never see after installing it seemed to be made of heavy gauge stainless steel.
2.  It works great.  All speeds are displayed on both sides, and with the remote blower very quiet.  The airflow seems very good, even at lower speeds.  At high speed it is quieter than the old nutone we had that was very ineffective.  Maybe a bonus, we got a set of halogen bulbs installed and a set of LEDs in boxes.  Haven't tried the LEDs yet, but the halogens look very nice.  On an ironic note, the oven blower is louder than the rangehood most of the time.

Note these are actual photos of the unit we purchased, not simulated pictures from the CAD program they designed it with, wish I had had a few before buying it.
