ATU Scooter

Hello, what do you think of ATU scooters? I’ve heard that there are some problems with it. I don’t want to screw around on the scooter or do anything illegal. Should they then perhaps last longer and not cause so many problems? I just want to go to school with it and sometimes also somewhere else, but never long distances. What about warranty cases and competence of the employees? Try to get people off from warranty cases or always fix them on guarantee ? Thank you in advance
