I used the enclosed wall anchors and screws and followed the instructions. It fell off the wall almost immediately, the screws were too small for the anchors so the anchors stayed in the wall and the screws just slid out of them. It hit my son on the head.

I managed to mount it again with other hardware I had at my house and it seems fine now but it seems like a significant oversight to include hardware that wont securely mount the shelf.
