As some of the other reviewers suggested, this unit had many installation problems. The installation instructions received from the manufacturer were not the same as those online. They were also incomplete as to which screws to use where and the purpose and placement of the small, clear washers. The holes drilled in the slats were too big for the supplied screws which necessitated a trip to the hardware store for bigger screws to attach the slats to the brackets. The slats also had to be cut to fit the cabinet door. Once all of the installation issues are worked out it's a nice unit, but you must be a patient handyman type to install it correctly. I also realized after receiving it that it comes in 3 different shelf widths. I probably would have opted for wider shelves if I had known this in advance.
