When you see this product on the website you don't get to know and see all the important details about the quality of itself. Only when you receive and personally inspect and test it before installing it. then you realize how the quality is poor. The motor it is all plastic covered and it is not balanced, causing extreme noise and vibrations when operating, especially on high speed. Also no details on the website, about the extensible chimney cover. I couldn't reach the ceiling when installing in a 9 ft. ceiling kitchen, the cover was too short, but then again you'll find it out after. You don't get to know these information on the website before you purchase it. In the end not so happy with this deal.
