This is disappointing to say the least. The instructions call for two different screw sizes - I was sent 4 different screw sizes, so not enough of any size to correspond to the pre-drilled holes. I didn't notice the size differences (aside from shorter and longer) until it was halfway assembled. The issue was made worse when one of the screws literally snapped when it was almost full screwed in (and the tool provided twisted!) - it was impossible to unscrew the remainder (and thus use a new screw) so only three corners of a shelf are secured. My last two complains are the gaps in the pre-assembled joints, and the super flimsy slats used for the shelves. The whole unit wobbles from a lack of rigidity in any of the pieces. I didn't expect greatness at this price point, but the lack of quality control and degree of cheap parts really surprised me. This was a failure all around.
