Product review (4 stars): The only one that fit our slim requirements
This really was the only range hood that fit our slim fit requirements.  Yes, we had to do a little creative cabinetry to fit the motor in the cabinet.  And the wall mounting and cabinet mounting could have been a bit more robust.  The exterior portion really flexes a little and we had to drill a couple of additional mounting holes so it didn't sag.  Occasionally the motor makes a little noise but a little whack on the motor shuts it up...I am sure a little realignment would help.

Noise: yeah, no matter what you do, moving that much air is gonna be noisy.  That being said, we were just happy to have an exhaust vent and tolerate the noise.  We have a direct vertical 6" round exhaust through the roof so there are no restrictions.  If you use the highest setting, you will need to crack a window if your kitchen is small.  That speaks well of its ability to move volumes of air.

The unit looks nice and performs well.  We really have found no need for the lights so we don't know whether we might have the same issue as others.  The filters are easily cleaned.

Based on code calculations, I think this also is one of the few units that pulls the required CFM for our new stove.  I can't remember how I came up with those calculations but a Google search will do you well.

The reason I rated this 4 instead of 5 stars is because the mounting could have been better designed with some extra mounting locations for fasteners.

One really nice thing is that their instructions are available online.

The finish seems very nice and the buttons feel good.  It's a little slow to start if you start it on the Quiet setting.

That being said, despite the small flaws, an enterprising person with the need for a super-slim installation should do well with this unit.
