The shelves came with plastic floppy levels.  They were NOT level.  Have extra holes behind the shelves in my wall now from having to reposition and move them to actually be level. after having to go out and buy a level to make the shelves even and straight. Biggest complaint is that the largest of the shelves does not sit flat against the wall.  There is a gap and it tilts slightly.  Wood material is quite cheap. Was marketed as real wood but feels like it's fake or man made board.
