purchased the 29ft3 4-door flex and love the looks! unfortunately, the sleekness disappears with the first touch as any touch shows on the stainless. it hides nothing. i'm cleaning it every night. my frigidaire professional hid everything.
i was concerned about not having a water and ice dispenser. i must say i love the constant fill water pitcher and find myself drinking more water. however, the ice maker is not as nice. it doesn't make very much ice and the ice it makes you push out the back when trying to get some. 
the flexibility of the fourth door is perfect for us. we have 3 chest freezers in the garage and needed more refrigerator space. this accomplishes it well. our refrigerator was always overflowing but not anymore. it's nice to see everything you have.
