Product review (3 stars): the good points. It's light weight
I bought this vent well informed of its shortcomings; the negative comments in other reviews were borne out in my experience.  First, the good points.  It's light weight, pretty easy to install, and reasonably well assembled.  It does a good job of drawing off smoke, steam, and cooking odors from our gas stove.

The bad points.  The sheet metal has two small dings that should never have passed quality control.  The touch controls provide a sonic beep with every touch; it's tone and intensity of a smoke alarm.  The vent fan itself is noisy, and the lights in the rear are useless.  I covered over the bright blue 24 hour clock with s piece of foil duct tape.

The vent has very real limitations; but I'm satisfied because of its low price.
