Product review (4 stars): Some installation problem solutions...
A great 5-star range hood, but a 3-star challenge to install.  It's heavier, deeper and taller than most hoods.

If you have to install it with duct fittings attached you may find (as I did) the mounting instructions are void: the slip mount slots may need more travel space than your last hood left you.

The electrical connections must be squeezed into a tiny black cube at the top right back corner--in a cavern of empty space.

The rear mounting screws slots are barely accessible or visible from below.  Tightening them is even iffier as they are buried 7" deep and parts below push your driver roughly 7 degrees out of plumb, causing the phillips bit to chew the screw.

Here's how I recommend installing it.

Pull the stove.  Trying to work over it will triple your work time and exhaust your vocabulary of expletives. Affix any necessary ducting fittings and put a plastic grommet in the electrical knockout hole. (No room for romex or cord clamps.) Drill 2 new 3/16" mounting holes about 1" inboard of the rear mounting slots to allow your mounting screws a straight drive.  Pre-strip the insulation from your connecting wires.

To mount: Lay a 2X6 across your countertops and from it raise the hood with spreader clamps or 2X posts with stepping wedges.  Insert the power cord and position the hood flush to cabinet & back wall.  Drive in the front mount screws in the factory slots.  Drive the back mounting screws into your custom holes using a cordless and 2 stacked driver shafts.  You'll need to illuminate these dark corners to find the holes, and to connect the power wires.  It's mostly black in there.

Lighting advisory: The 6-watt LED lights recommended by EricinGA work great and are much easier to install/remove than the halogens because they're 1/4" longer.  But if you're fastidious about styling you may resent the protrusion in an otherwise smooth surface.  Finding a shorter LED won't help: The suction cup for installing the (flush) halogens slips off LEDs.

All caveats aside, I love this hood.  Enormous suction, great lighting & controls, makes less noise on high than the old hood did on low.  I'd buy it--and even install it--again.
