Product review (4 stars): Great price on a powerful, well designed range hood.
Overall it's does take more time than expected to install (does take two people), and the directions leave a little more to be desired. But this is probably the case with all range hoods.

This is a single fan, 760 CFM unit that offers 4 fan speeds, two halogen lights in back, and a timer feature to turn off the fans. A few nice points are that the look is very "gourmet" with the vents and handles for the grease traps, the lights tip so that they can be adjusted to point at the food or reflect off the back splash, and the buttons are very simple. It also comes with two nice long, nested pieces of vent shaft for high ceilings.

Here's some tips:
1) you'll need duct tape, and possibly more ducting depending on your application. It comes with a fairly long duct already though.
2) really measure out how tall you're going to position the range hood, keeping in consideration not just the height above the cooktop, but also the vent shaft too. Too low, and there may not be enough shaft. Too tall, and you may not be able to mount the shaft using the predrilled holes.
3) plan out where your outlet will be... the duct and mount on the fan are very close to the back wall, so make sure the outlet / power cord can clear it.

I did find the ceiling mount for the vent shaft to be too short for easy assembly. Unless you're trimming around the shaft, you'll need that bracket all the way up where the wall meets the ceiling, leaving very little room for you to screw in the shaft to the mount.

Finally, the fan speeds are great - lowest setting is still strong, yet quiet; and the max setting is powerful. Fan is mounted in the range well because I didn't experience any vibration.

I did have to re-connect the button controls to the main power connector before operation. It didn't turn on, so I had to troubleshoot the issue - luckily wiring is exposed and not hard to figure out.
