Product review (4 stars): Prep prep prep
So far so good,was not too hard of a install for 1st timer (utube is very helpful too).

If you are not going to hire a contractor (even if you do), decide if you want wall or roof venting (recirculating is just stupid and pointless).

I chose to wall vent (since it's easier, no going into attic/crawl space and no going on roof...I nearly shit myself a couple times last time that I went up on my roof).  There was already a electrical box wired in my cabinet. I decided to cut into my cabinet and use it to hide the chimney instead of using the stainless steel chimney covers (and will probably use back splash stickers to cover up whatever is showing)

Took about 4 hrs to install myself... Just need to add beautification finishes and will be less of an eye sore.

Fan noise is noisy at high and medium, low is okay, since it is about 28" from cook top, low will be fine for cooking unless the SO is frying, then high it will be. Time is easy to set up (I didn't read/need instructions), so all the people saying that time is hard to set up are probably not intuitive. The 2 led lights have a good daylight color temperature (same as all my house lights) to them and are bright enough for the cooktop.

CONS
-it looks like I got a returned unit (some scuffs and masking tape on cord like someone repacked it)
-the screws and anchors (laughable that you would anchor something this heavy into dry wall) are cr@p.  MFG's selling heavy things that need to be mounted onto walls need to stop providing dry wall anchors (giving inexperienced folks the wrong idea that the item can just be mounted to dry wall).  Go get better screws from your local hardware store AND MOUNT TO STUDS OR SOMETHING SOLID (please don't mount to dry wall)
