Product review (5 stars): Finally able to use that wasted door space!
Fits my Whirlpool WRS571CIDM01 model perfectly.  This fits on the refrigerator side, not the freezer side.  Anyone who owns one knows that you get shorted a door bin, leaving a big gap where a shelf should be (and wasted space that is a premium for a counter depth fridge).  This door bin has white trim, where my model is all clear plastic.  However, making this the bottom bin on the door offsets the bins not matching, since the top bin and drawers have white trim as well.
