Product review (5 stars): This is powerful and cost-effective range hood for Chinese food
I'm Chinese, after comparison on price and power airflow,  I choose the cost-effective range hood,  after installed and have 2 week usage experience, I write review as following: (1). This is real high cost performance hood, work very good for Chinese food. (2). As the installation guide said, a minimum of 6'' round duct  must be used to maintain maximum airflow efficiency, if use 4'' duct, the hood work so poor. (3) The baffle filters have lot of scratch as image  attached when I received, I think it was not brand-new,  and I ask to exchange the baffle filters.
