I am a teacher and I always had a briefcase in one hand and a bag in the other bags on the shoulder ... Here I put everything in my briefcase on wheels and I walk the halls quickly and without pain! It is well designed, I have my highly ranked pens at hand, my calendar, my pockets each in its compartment ... Everything is organized! The only problem are the stairs: careful not to overload the (but with detachable pages manuals, one can easily get around the problem). Also, one of my colleagues with the same for several months, I think it is really solid. A purchase I do not regret!
