I bought this a few weeks ago. At 900CFM it 's certainly a bit noisy then my old one. But that old one was only 450CFM. So it's normal. It work great. The light is make really clear to see what you do on the stove. I'm really happy with this unit.
I HAVE USED MY HOOD FOR JUST OVER A YEAR. I LOVE THE LOOKS AND THE FUNCTION. THE LOW FAN IS JUST A BIT NOISY AND IT WOULD BE NICE IF THE "LAMPS" WERE JUST A BIT BRIGHTER BUT ITS MUCH BETTER THAN ANY OTHERS WE LOOKED AT.
