Product review (5 stars): Great product in Design and Useful Fuctions
It is the great product I need. And I like its design and functions very much. What made me to buy it when I was search for the similar products were: high flow rate (max. at 450 SCF), and the function of heat sentry design. After opening the package, the blowers design and a large opening space inside the hood (i.e. Large air way) and the indicator lights in the front for power, lights, filter, and blower speeds, and timer etc are good points of design. In addition, the height is about 1 ft (more than 6" higher than the other brands), which means it is more than 6" closer to the stoves, and increase suction capability for cooking "smoke". There are three speeds of suction flow rates. The highest flow rate is the bonus one (Note: not many other brands give you the specification of flow rates). The blower noise is similar to the fan noise in our house rest room.  When testing, it is clear to see the cooking "smoke"  be sucked into the hood. The price is right to me. In summary, my wife and I love this product, and will strongly recommend my friends to buy it.
