Product review (3 stars): It's hard to explain here but basically there is one bracket that looks like this [ when there should be 2 to form ...
This unit is of mediocre quality.

First: the entire hood only secures to the ceiling on 2/4 corners or one side of the box at the top.  The brackets to hold it to the ceiling are only on one side.  It's hard to explain here but basically there is one bracket that looks like this [ when there should be 2 to form a shape that looks like this []  This means that every time you touch the unit it swings a little.  It never feels fully secure to the ceiling.

Second: the control units for the lights and fan are of subpar quality.  When my unit arrived only one of the 2 light controls worked.  Which meant I could only turn on the lights from one side.  The broken light switch now works intermittently.  I will be contacting the manufacturer for a replacement switch/control unit.

Keep in mind this is one of least expensive island hoods on the market.
