I am a nursing student and needed a book bag that would carry my books.  While it does not carry all of them, it carries all that I need for the given day. The wheels roll super easy and the convenience can not be matched.  I am so pleased with this purchase. I could not imagine lugging this weight around on my back/shoulders all day! (and this is an option with the tuckaway straps that tuck inside the back. And the bag is pretty too...;)
