Product review (4 stars): Any ductless unit has limits
I am only speaking for the ductless use of this product. One can not expect the odor and heat removal of a ducted unit. People who wok, grill, and fry a lot with heavy spicing should go ducted and get a restaurant quality unit. I recently replaced a Jenn Air gas range because the onboard exhaust was so strong it sucked too much heat away from the burners, necessitating the purchase of this product. This unit is well made, very attractive, and it fully covers the cooktop area. It was relatively easy to install although a little help from a second person was enlisted. Bulbs snapped right in, and lighting is good and well distributed, although I like lots of light and will add more. The filter frames fit well into place, and are easy to install and remove. The suction is marginal on low but adequate on high, and the noise and vibration are low. I would have given the fifth star for a little more power,  rheostat fan control, and some type of trap or secondary filtration at the output.
