Product review (5 stars): really beautiful and works GREAT!  It is NOT super noisy
We really LOVE this unit.  My husband installed it all by himself.  But he is very handy with all kinds of things which is really great. But I mention this because you can do it by yourself and do NOT need 2 people if you are clever : )  at one point he used  a couple of boxes to hold up part of the "stack" of the unit so he could put things together and secure it to the ceiling etc.  It is really beautiful and works GREAT!  It is NOT super noisy at all and unless you have it on the top speed you won't even know it is on.  But at top speed of course you hear it but it is not super loud.  I can't stand crazy noisy appliances which is one of the reasons we bought this unit.  It has POWER but not too loud.  and the LIGHT works AWESOME!!  I can really see what we are cooking on the stove.  LOVE LOVE LOVE It and highly recommend it.
