I am a contractor and have put in two of these in the past month.  Everything is good about it.  Noise, installation, quality, shipping.  The optional chimney sizes and the crown put it over the top.  The only thing i did not like about it is that the lights are on the back.  We did a full granite backsplash which is about 1 1/4" deep.  The lights touch the backsplash and cannot be moved.  The light also highlights the seam in the granite that we had to put in this case.  I am sure that if it were a tile backsplash it would do the same by highlighting any imperfections in the tile by shining a light straight down.  I will be reccomending this to another client soon, but will give a warning about the light situation.
