Product review (4 stars): I like it and love the middle drawer
I have the FR30 version of this refrigerator (larger) but everything else is the same.  I like it and love the middle drawer.  I've had door in door before and the newness wears off quickly.  It does cool down very quickly and the LED lighting is nice but they neglected to take the lighting to the rear of the unit.  When you have such a large refrigerator, the lack of lighting is an issue. It is extremely quiet.  We didn't even realize it was running when we first plugged it in.
Now the cons:  as stated, the lack of lighting in the rear of the inside, no auto nightlight at the water and ice dispenser, the ice maker is SLOW.  It is slow making ice as well as you have to stand there forever to get a glass of ice whether it is cubed or crushed, and there isn't a flat grid to sit your glass on while waiting for the ice to finally fall. Also, the water lever behind the ice one is annoying.  I would advise people with children or teenagers not get this unit as the doors will not close easily and if not shut firmly will slowly open back up, making it hard for children and teenagers wouldn't notice.
These problems are with Samsung design as they exist with my neighbor's Samsung and also my son's unit and they have different models than mine.
All in all, not a bad fridge but a little pricey for the lack of amenities.  Love that third drawer though!
