the seat has good ratings on the ADAC. The Plus is that the child is restrained by the seat belt car is intended for adults while children harnesses are provided for children are therefore more resistant MAYBE. But especially in the event of a frontal impact the child's head is powered on module which happens quite close to his head and so 'bounced'. So a "better" impact. Son - is that when the child pushes the module, it disconnects. I also find it unfortunate that there is not a third attachment point to the car. There are two Isofix hooks and in addition there is a lot of the same game, of course, when the seat is attached correctly. It is good for its module but again I do not think I'll buy it.
