This is a great little bag. It has shoulder straps for carrying and wheels for heavier loads. First time I used it I got a ton of questions asking where I got it and if it was light weight. You can easily carry it on your shoulder as a "tote" when empty or when full if you have to navigate stairs.  As a roller it rolls easily and the wheels and handle seem to be sturdy.  The inside is not "fancy"- a big open space.  The black dot pattern is cute yet will hold up to grimy subways. Its a good bag for the price.
