This shelf is as advertised. I took off a star because the rotating mechanism on mine wasn’t smooth at all. I read other reviews and didn’t see anyone else mentioning that. I took all the books off, removed the bottom piece and sprayed some WD-40 which helped a lot. 

As you can see from the photo, I didn’t assemble it correctly in terms of the side panels but I’m too lazy to disassemble it and fix it and it doesn’t bother me that much. 

As others have mentioned it doesn’t fit larger children’s books, so those will stick out the side or just won’t fit, so if you plan to store those size books, you’re better off choosing another one.
