I was remodeling my kitchen and purchased this early on.  THEN the cabinets were installed and the garbage disposal... long story short, the unit wouldn't fit... and it was too late to return it.   Luckily, because of the quality of Super Human, I was able to use the pull-out frame with a little tweaking!  I cut down the metal 'frame', rigged it to hold just the black can and a box of tall kitchen bags behind the can.  It pulls out like a charm!  The blue can sits under the left side of the sink.
