We were convinced by the principle of rückwärtgerichteten driving. For our 20 months daughter we bought half a year of this model. Sure, the rotation function is convenient and the seat looks well made and sturdy. This requires, however, a heavy weight that you can complain to any removal and installation. The serious shortcomings of the seat, however, are elsewhere: 1. the seat even for petite children quickly too small. The child has the legs unnaturally bend in order to get over the safety rail at the foot end. That's uncomfortable on short trips and in my opinion a health risk, but on long journeys, it is a pain for the child. 2. The straps do not stay right on the shoulders of the child, they slip ever right and left down the arm. In an accident, the child would not stay in the seat. From my perspective, the seat is therefore a bad design and although the manufacturer recommends to drive backwards up to 4 years, which is not possible under normal conditions. The manufacturer had no desire by the way, to deal more closely with my findings. Likewise, the ADAC, which has bestbenotet the seat. Completely incomprehensible! They had certainly never sit a true child in it!
