Product review (5 stars): Pulls the smoke and steam right out.
The fan performs and looks very nice and well.  If you are putting this in yourself then read on!  The directions that came with my unit seemed to be an adaptation of two different units and there were a few things lost in translation.  If you have a lower ceiling then you want to make sure the brackets you install are high up enough for the power head unit to slide completely in place or you will be taking it down and doing it over.  The flex duct they give you is worthless and I would suggest (as they do) to go with a solid pipe.  Most other items are easy enough to figure out and be careful as the stainless top is SHARP.  I was ready for it and it still got me.  The bulbs that come with it don't last long and if you get LED versions make sure they have glass on the front AND are not too large in the middle as they will not fit into the hood all the way preventing you from placing the lock ring on.  So, why 5 stars and still all this, It was much cheaper than many other units and had the same look and function.  You cannot tell what I paid for it by its looks and it looks great with my remodel.  I feel I got what I paid for and fan function is very good at 900 CFM and on my unit the lights do not dim which i did not care about.
