Product review (4 stars): AK7100AS-BF
Others are correct, install is tough, but not impossible.  Just need to measure exactly and be precise.  I had to install furring strips beneath my cabinet so there was something for the wood screws to grab onto.  One tip for installation, I strongly suggest using washers for the supplied wood screws, as the slots on the hood that the screws fit into is a little wide and it feels like the heads on the screws aren't wide enough.  The washers add quite a bit of strength and stability, kind of surprised they weren't supplied by the manufacturer..  I think the hardest part of the installation was getting the light bars removed... I ended up having to use a small flat head screwdriver to break it free.

As for performance, I was concerned that 400CFM wouldn't be enough, however I am very pleased with the performance.  Other reviewers noted that the unit is loud, and while I wouldn't say it is loud, you can definitely hear it running even on low.  That said, we were replacing a microwave range-hood combo which sounded like an F-15 flying over the house, so I'm not complaining about the noise.  We had an HVAC Contractor vent the hood straight up thru the ceiling and out the roof, no more smelling dinner for hours after it is cooked!  The baffle filters are easily removed and the halogen lights are bright and dim-able, though I will probably replace the bulbs with LED at some point.

Finally, I had reservations about ordering this from amazon because of potential shipping damage, but the product was packaged well with plenty of Styrofoam and had protective film all around the stainless.  There was a slight ding in the corner but it was the side against the wall so I installed it anyway (which was why the halogen light strips were so hard to get out, they had been wedged in by that same ding).

All in all I give this 4 stars... would buy it again.  Install could have been a lot easier and unit could be quieter, but overall I'm happy
