Product review (4 stars): Not Great, but Very, Very Good (or "you can't have everything, can you?")
So first things first...none of the dimensions shown are correct. It is shown as a 30" range hood, but the actual width is 29.5 inches. The height is (I think) listed as nine inches, but you can tell by the photos that it is not. I can't recall whether it is 4" tall or 5" tall, but I do recall that it is one inch less tall than the old white Broan range hood I replaced. If you look at the picyures and the cut outs on the back, you can more or less guess its acual height.

That's the bad...now, the good...

First, the look. I had to center it due to it being 1/2" shorter (less wide) than what it replaced, but I have to say, it looks great. I love the look and tactile feel of the buttons up-front; it's a very clean and understated design.

This thing is capable of moving quiet a bit of air; the various speeds coupled with the two fans probably;y means that this will never lag in terms of exhausting the heat and odors from your range. One thing is a bit of a misnomer to me, and that is the "Q" (Quiet) setting; as a noise and vibration Engineer, I have come to learn that 'quiet' is a relative term, and this is no exception. In fact, I would have liked (preferred) another speed that was 1/2 the rate as that on the "Q" setting, but truthfully, I am willing to live with the additional noise because it does what it is designed to do - reject heat from the range area - very, very well. On the highest setting it's quite impressive but also loud. This makes sense because moving a lot of air in a very quiet fashion is easier said than done.

Again, all in all, I really like the looks and performance of this, and my sole caveat is that I would have preferred a "Q/2" speed setting, but as the French say... c'est la vie.

Aesthetically, it looks quite nice - even from the underside. The grilles look...well...'the business' (as the Brits say) and much more professional than did the grill on the Broan range hood that I replaced. I really like the look of the grates.

The LED lighting is also nice, and again, this is a feature that, like the "quiet" fan setting I wish had a setting that was 1/2 as bright (for very late night use), but that's a matter of preference. In terms of illuminating the surface of your range or cook top, it should do the job nicely.

All in all, I really like this. I could not give it five stars due to the two main issues that I mentioned (the half-speed and half-brightness wish list items), but if I set those aside, overall, I am really happy with this purchase. It's a subtle change but it really change the look of that area of my kitchen. I should have bought this long ago.
