Product review (5 stars): Happy Owner
My only problem with reviews is most folks only take the time to write bad ones to vent.  I bought this unit about 1.5 years ago.  Overall when people buy, Viking, Wolf or a BMW, MB... they are forgetting that these are premium products pushing the envelope in terms of performance and features.  These trend setters often test out what works years ahead of `mass market'.  For perfect reliability and average form buy the middle never the top.  Just don't forget 5K is still upper middle.  Built ins run 12k and up in some cases.

Astatically
I love how this unit goes from the floor to ceiling giving the built in look.  Its hard to find a flush counter depth which fits like a glove.  This looks like a 10k unit at half the price.  Any stainless appliance is hard to keep clean.  Working in a kitchen for 8 years we wiped down appliances throughout the night and every night we polish all the equipment.  I never understood why the consumer market wanted the commercial look.
When entertaining I am constantly complimented by the appearance.  Few counter depths have this much storage or can fit a pizza easily on the shelves. The interior lighting is one of the best but that is just an opinion.  My only ding is the freezer light is on the fridge door.  Occasionally I leave both open while unloading supplies.  As such, the fridge is internally lit the freezer is lit from the underside of the door thus underwhelming.
Functionally
The freezer drawers work well rather than digging to the back to find green beans which have been frozen for 5 years with my older units. The machine is silent.  I have a dedicated gourmet kitchen with eating area.  I wanted silence when running the dishwasher and when the fridge kicks on.  This was  HUGE draw for me with this unit.  While the dual compressors keep the food at a constant temp I hardly know when it kicks on.  The additional fan mode keeps air moving to reduce moister as is a problem with many of the new fridges.
I opted for the internal icemaker.  While I sacrifice some storage cubes use filtered water (pretty much standard now) and are good size.  I have yet to run out or have any issues with the icemaker.

Mechanically
I am very pleased.  The Bosch, and Miele were the two alternatives I had looked at.  If you look at the design of the dual compressors the lack of variation keeps food fresher longer.  I learned while doing my research that cheaper units tend to vary more in temperature.  Some friends have knocked this as a faux performance issue but at 33 you have water at 32 ice.  A slight degree variation makes a large difference with respect to bacteria, and the cells in meats and veggies.  I have noticed better food storage when compared to my $1700 fridge which is now in the basement kitchenette.
I have not yet had a problem with the alarm yet but I have left the door open and been woken up at night by the beeping.  Simply pressing the silence button and closing the door has saved me more than a few loads of groceries.  I bought from a reputable local buyer who handles complaints so I have no fears when/if something should go wrong with the unit.
