So far, so good.  Island configuration.  Good lighting from the 4 high-intensity bulbs (what a difference when cooking!) and good venting - highest speed not too noisy but still somewhat of a roar as expected.  Installation went well - 2 people needed to handle the weight.  As no ceiling mounting hardware is included (everyone's situation would be different) needed to spend some prep time on designing wood blocking, in our case, to screw the hood to.  Vented to outside - included instructions helped with this but you need to engineer your own solution.  Actual installation took one long afternoon and finished project looks great - wished we had done this years ago.
