Product review (4 stars): And this vent hood really sucks. (Air
very well design/built. looks good/solid. Noise level is acceptable. The motors themselves make very little noise. It's the air movement that generate most of the noise. And this vent hood really sucks. (Air, that is).
The problem I had was one of the blower is off balance, making it vibrate really bad. I called the manufacture and a blower is on it's way to my house to resolve the issue. I guess someone from the QC dept failed to do his/her job.
