Negative strikes me:
The handle for pulling out is quite shaky. If one is larger and the trolley rather steeply behind drags he comes often skidded because you through the game under control too little control.
For some time, the mechanism for retracting the handle is broken and the bar can be completely pushed back only with much fumbling again.
The front feet are hollow and the caps are fairly thin. The support feet are now worn through with me and the caps off. It collects dirt there now.
The front pocket for the laptop has a division that is wobbly and anyway always shifts.
The Trolley is definitely no hand baggage on the dimensions. You could make it narrower if you could take off the backpack straps. This I once needed. In recent times I experience it more often that the trolley was no longer accepted as hand luggage (eg German Wings). Also have to say that with complete equipment and notebook here ruckzuck 16-18 kilos come (which is then in the nature of things.) On the scale.
But for lack of alternatives is still a viable solution.
