Product review (2 stars): Technically functions but crap build quality
The first one of these arrived with a corner dented in and a few of the spot welds popped, so I sent it back.  The second one had one spot weld popped but nothing was dented so I tacked it back myself.  I luckily have access to a TIG machine as the sheet metal is very thing and it would be pretty difficult to fix anything with MIG or stick without burning a hole in it or something.  One of the removable vent panels was also broken (the latch spring had come out and was nowhere to be found.  I had to get really creative fixing that one.
Additionally, I had to trim the upper shroud and angle brackets because, as it comes, the highest this thing will hang is crazy low.  Even if you have high ceilings, you'll want to shorten this thing beyond it's shortest setting or else you'll have a hood right in your face while you're cooking.  Again, luckily I have fabrication stuff so I could trim the pieces correctly.
Once installed, the thing has no built-in adjust-ability to get it level.  In most houses not everything is perfectly straight and when you're screwing stuff into the ceiling, there will always be a small amount of angular error. A small amount of error on that smaller bracket that goes on the ceiling translates to a large amount of error on the wider, lower part of the unit.  I ended up having to take it apart, loosen the screws, shift some stuff around taking advantage of the oversized screw holes, and then tighten them again.  A few iterations of that got it level, and then I drilled some holes of my own for pins to hold everything level so it doesn't slip further.  Due to the way this thing is designed, this part was a huge pain.
Also, not that I was planning to use it much, but the remote that comes with it is crap.  You have to press the buttons really hard and hold it at just the right angle and it still only works sometimes.
Having said that, now that I have the thing properly modified and installed, it does work. The on-unit controls on both sides work fine.  The fan works and isn't crazy loud, and the lights work fairly well.  This thing gets 2 starts instead of just 1 because of that.
If you have the skills and equipment to fix any problems and/or have the patience to send the unit back a few times until you get shipped a good one, then this could work for you.  For most people, though, I would not recommend this unit.  The poor build quality just makes installing it correctly more trouble than it should be.  Most people that I know would not be willing to deal with it.
