We've had our 4 door Flex for a couple months and absolutely love all of the features! We weren't sure about the beverage compartment, but are finding it very convenient. The auto fill water pitcher is so useful. Milk, creamers, etc. Are easily accessible.  Even better, the icemaker keeps ahead of our needs, and with two sizes of ice cubes.  Freezer space made for easy access and optional fridge side will come in handy. 
Best decision we've made!!! Highly recommend.
