Product review (5 stars): Decent price, looks good, been great for 2 years so far
I replaced a 1970's fan that just blew in my face with this unit, and ducted it outside.  Installation was mostly easy if you're replacing a similar size unit and handy with basic tools.

Lights are fantastic. I used 50w PAR20 halogens I think, and while they are hot, the 2 light setting is enough, and 3 is like sunshine (used when I use the stovetop for a prep area).  When they burn out, I plan to replace with LEDs at about $20 a pop (halogens were $4-5 each).  I've had these halogens in for 2 years, using them daily almost, and they're still kicking.

Build quality is good.  Easy to clean.  First speed is unnoticable, noise wise. 2nd speed you can hear it if you don't have anything else going on in the kitchen.. 3rd speed is noticeably loud - like I wouldnt leave it on while watching our small TV in the kitchen.
That said, I use the 3rd speed to clear out smoke, cooking bacon, and stiryfry'in.  That's it.  #2 speed is plenty for a has range and most uses.

Only complaint that I barely think is a complaint is the automatic turn-on to high speed fan when it detects high temperature.  Some folks seem to find this annoying and think it comes on way too much, I've only ever, ever, ever, had it come on when I forgot about something on the range and it started smoking and got hot, or I leave a burner on without a pot atop it. The 4 or 5 times this has happened in the last 2 years I am happy it came on - because it reminded me to go turn something off.  Maybe the sensor is quirky for some folks or mine is quirky - but I can't imagine cooking as much as I do at super hot gas temps (woks, heating salt block, etc) I wouldnt have been annoyed if it was really too eager.
