Product review (5 stars): Good hood. No issues I could find. I'm quite picky, too.
Low fan is very quiet, just loud enough to be heard (which is actually good, so you won't accidentally leave it on forever).  High fan is fairly noisy, as I believe all fans are when they move lots of air.  Perfect -- I use the low setting when cooking smelly food, high if I really need to move a lot of air.  The four lights are veeeery slightly angled inward, so this doesn't quite work to illuminate the counter on either side as well as I might have hoped, even if you pick lights that are "floods" not "spots".  The cabinet's slope in front seems to minimize the possibility of bashing your head as you cook... mine is installed just above my eye level, and I have not hit my head. (A friend has a different hood, is always hitting his head...)  (specifically, top of hood is at 5'10", I am a bit taller than that, never banged my head!) The rocker switches are fine, I like them. The "off" positions are with the rockers pushed in at left, not the "even" rocker position; thus it is easy to turn them off with a single finger jab e.g. when holding a hot pot in your other hand.  Pushed in at right, the rockers are high-fan or high-light.  Pretty easy to take down the screens for cleaning (dishwasher safe)

I called the company to ask about LED options for the four lights (which are GU10 format, btw., you must buy the specific halogen types called for, not hard to find at Lowes or Home Dep)  Cust Srvice seemed very competent and on the ball, not someone reading a script from overseas. They explained that as of yet they know of no LED whose ballast portion can survive the heat of a typical stovetop for long, and therefore they do not use electronics that will support LED GU10 bulbs.  So with this hood, you are stuck with halogen bulbs (I bought 50w ones rather than 35w ones, find low setting fine. High setting quite bright but not too bright).  Broan said they are actively searching for LEDs that are designed to withstand stovetop heat for extended periods, but they know of none.

My contractor said it was an easy install.

I've updated this review -- had the hood for about a year now with no problems.  Stylistically it's great, matches any kitchen I could think of, does not have a cheap look at all.  Greatly appreciate that I have a cupboard over this hood rather than the ridiculous hoods that preclude cupboards.  Glad I spent the time looking at every hood in the big stores, didn't like any, and took a chance on this one.
