Product review (3 stars): Good - while it worked
This was a very good fan.  Strong exhaust, not too loud (5.5 sones).

So why not 5 stars?

2 reasons.  First of all, it uses expensive lights that burn out very quickly.

Secondly, it died after only 3-4 years.  We are not a restaurant, just a home.  I would have expected a longer life for a product this expensive.

If it lasted longer and the bulbs didn't constantly burn out I would have given 5 stars.

(by the way, I am going to try the Skylinex range hood next.  I have never heard of it, but it is only 220 bucks direct from the manufacturer, and it is 810 CFM.  Downside - 13 sones - very loud.)
