Awful. The screws are too long for the shelves and the shelves are made of incredibly cheap material. When you screw in the shelves all the way so that they rest on the metal support bar and so that the screws meet the bottom of the bar, you end up wrecking the top of the shelf, leaving an unsightly hole and exposed screw. 3 out of 5 shelves are ruined. The other two are not, but the screws do not fit tightly. This thing should cost $5 and not a penny more. Save your money & time.
