Product review (3 stars): Some good and lots of bad
I struggled giving this a 3 versus a 2, despite that I'd probably buy it again. If it had some small inexpensive redesigns, I would be happy to pay fifty dollars more for it.

The good
Attractive 1960's look (except for the obnoxious Kaze Logo)
Very thin profile, with rounded edges that don't hurt when you bump your head against them
Serious suction power with a solid sound (no rattling)
Plastic damper exactly fits the non fluted end of 6" metal duct, and has a high quality seal. Best I've ever seen.

The bad
It is really 35.25" My old vent hood was a full 36". I understand having it 35.75" for adjustment, but 0.75" is too much smaller.
The worst instructions I've ever seen. They're not worth the 10 cents in paper they are written on.
No template is included. I mounted it to a thin piece of plywood so I could make mistakes on it, and then used it as a template to cut my bottom cabinet. Idiotically the shroud/damper is not centered left to right on the case. It is about 1" off making installation harder without a template.
The sheet metal is very thin, it really needs to be one gauge thicker to reduce flexing even after installation, but it is tolerable.
The front mounting screws barely fit under a 12" deep cabinet (like within a quarter inch of being into the door frame if you take off the stupid plastic spacers at the back of the unit that serve no good purpose).
The front top of the unit sags enough to leave a little more than 1/8 inch gap in the middle under the cabinet face. There isn't a way to put a screw there because the fan case is in the way and not removable. It should have a reinforcing bracket inside across the front, and the fan case should be moved back about an inch to accommodate this. I ended up filling it with brown caulk.
The edges (especially the bottom panel meant for regular cleaning removal) is razor sharp. I got a serious bleeding cut the first time I removed it.
The fan case should be removable from the top unit instead of tack welded in, and the shroud/damper should come out with the fan case instead of top mounting. That would make installation massively easier, especially without a template.
The light would have a much better throw and be easier to replace without cutting yourself, if they made the cutout a couple inches bigger.
That ugly blue and yellow Kaze logo isn't just glued on. It is drilled with 2 posts. You can reach behind it and bend the posts to remove it, but it leaves 2 small holes in the front of your hood. If they had just made the logo chrome, it would have been tolerable and I would have left it.

Smaller things
Don't bother using the included incandescent bulb / scalding case heater, be sure to get a CFL or LED light.
The electric box is super tiny to deal with, it would have been much easier if they made it bigger, and there is plenty of room to do so.
They put a rubber grommet around the electrical entrance. It is an unacceptable design because it prevents flush mounting to the bottom of a cabinet unless you have an 1.5" or bigger drillbit, which I didn't think of doing until after the fact. Got to find another way to protect wire entrance.
Many of the screws (that you don't use for installation) in the whole unit were loose.
They didn't bother to secure the wiring with the metal retention tabs installed throughout the case. They left some wire wound up directly above the incandescent bulb to get scalding hot that I had to reroute.
They included some hardware like wood screws (they only included 3 where you must have 4). The wood screws were entirely too long for almost every cabinet bottom in existence. They would poke into your cabinet.
Small dumb things like these seem to show a lack of commitment to their product.

In the end it got installed with a lot of cussing and a little damage to my cabinet and fingers. It looks good and works. But it has so much more potential to be an impressively good product.
