So far good. No complaints about it except template provided for installation is not correct. it has to be updated with correct dimensions for location of holes etc.
But as far as exhaust feature it is 5-Star, no odor of cooking. it is best for Asian (Chinese or Indian) cooking. I was using for last 3 days and I am happy with it. I will update after a month and based on my experience I will modify the STARS (right now not much usage I can't give 5-stars)
