Product review (5 stars): Very happy with this hood (update:  still very happy)
Well built, quiet, powerful.  Very happy with this hood. Had to reduce duct to 6" for last few inches, it still flows a ton of air.  Looks great, install directions well done.

Update a month later:  push buttons have a nice solid click. Work with wet hands.  Hood is easy to clean, very solid performance. I find myself leaving it on and thinking it's on 1, but it's on 2 (medium).  It's quieter on full blast than my old microwave/ hood combo was on low.

No issues with my duct squeezing down to 6" at the outside discharge. Still moving tons of air, no weird airflow issues.  The rounded corners have saved each of our foreheads a couple times. Nice touch for function and looks.

This thing is very solid. My next option was a $1500 external blower setup-  this is delivering the performance I needed at a much lower price and with much easier install. I did it in an evening, no particular rush.

Since its heavy and I didn't have a helper I covered my stove top and put a motorcycle jack there and lifted the hood into place with that. Worked great, just as shown in directions.

LEDs are bluish. I'd prefer whiter LED but in normal use this is a non issue. Good, even, bright light.

Update:

After a year still a great hood.  There's a but coming. Have had trouble with LED lights burning out.  They have multiple LEDs in them and after a while 3-6 of the 15 LEDs in each module failed.

Xtremeair mailed me replacements in November 2015 (bought hood in August 2015).  I just emailed them again (august 2016) regarding needing another set of replacements. I expect this to be easy like it was last time as I'm still in 2 year warranty (blower 10, the rest 2) but I'm concerned if this keeps happening, what about 2 years from now when I'm out of warranty? I don't see the bulbs for sale directly at retail anywhere, although I do see lots of chinese manufacturers selling them on their own sites.

It's a 12v module so worst case I can cook up (haha a pun!) a replacement light unit but I should not have to.  I am hopeful Xtremeair has found a better LED light supplier with an improved light.... we shall see.

Update June 2018.  I have LED light modules flickering again...  Im hopeful Xtremeair steps up with replacements again, and hopeful these last longer than the previous set, which was definitely an improvement over the initial sets.
