Did the trolley now for a quarter in use and do not want to miss him. Light, handy, waterproof. Roles are well steered and the guide rod for body size 175 suitable. In addition to the laptop compartment, there is another compartment for books, binders, etc. This should also be filled because if only the laptop in it, loading one side and the trolley tilts when turning off towards man. Therefore, a star deduction. By design, fast, not as conservative as the square laptop trolleys, yet suitable for business. Have him only as a trolley in use, not as a backpack.
