I have had this hood installed for about 6-7 months now.  I use it all the time.  The hood itself looks amazing.  

The reason for the four stars is because the fan is a little loud.  Granted, it does work quite well, but I wish it was slightly quieter.  

Another small issue that I had with this range hood was the metal grates would rattle.  The solution I came up with was to put a small rubber band between the grate and the lip of the hood.  That has worked perfectly until I have time to come up with a more permanent solution.

Overall, I don't have a problem with this range hood at all. I would buy it again, but I would also try to find something slightly quieter.
