Product review (2 stars): Kind of pathetic, actually
We've had ours for 12 years now and I am not much of a fan.  Pay close attention to how high up you mount it... our idiot "CKD" designer had it originally 5" higher than the top spec (believe that was 29") but thankfully our carpenter noticed how high it was and built an adjustment panel to bring it to spec.  But still, if we do something dramatic involving lots of heat and smoke, the kitchen is one smoky mess and the alarms all go off all over the house.  Kind of pathetic, actually.

Even when doing something less "dramatic", I always find that, even on high, I can look left and up to one of the ceiling lights, and see a fog of smoke/fat wafting around.

Not really impressed.  Now the pushbuttons are really hard to work; you have to just mash on them to get fan or get light... and since the replacement board is $193 or so, damned near the price of a new unit, we're looking elsewhere for a better hood.  I wish I had researched this more but you live, and you learn.
