Useful storage space for my pot lids and larger cooking utensils, but the arms do prevent my doors from closing all the way.  Make sure your cabinets have the clearance space to fit the arms and still close snugly. There is a groove in the arm that extends approximately 1 inch, so if the framing around your cabinets is less than 1 inch from the top of your cabinet door, your doors will not close perfectly.
