It is here in the reviews everything already in there and unfortunately I have to confirm. This base is not worth the money and also still stellr a security risk has on the Isofix Verankerng too much play and hence wobbles when driving back and forth. Sits a kid in there, it still goes. If you go with an empty base you will be insane by the sound. Also, the alarm goes on when you drive something too strong in the curve ... Precisely because of the game, the base tilting upwards in a serious accident or rollover - quite fatal! But it has a stand forward, whose meaning does not want to open up to me. It's for nothing good, except that children who want to get themselves into the seat, constantly falling over it and the seat can not be used in cars with ground subjects. Certain seat inclinations allow the use of the base is also not to - so for example, in the typical family car Touran - we just bought one. Really great. And the best: the lever for releasing the child seat / infant carrier is once canceled (and that happens with such plastic parts sometime guarantees for wear), then you get the baby car seat (or the child seat) no longer resolved. So plan ahead up to the second child should not be with the base. All in all I do not understand how you can find this base well. In an accident the child has virtually no protection. This really is fatal!
