We bought mounting because of the good test results this infant carrier incl. Isofix and can not recommend this combination. As widely criticized the baby seat tilts quickly in the base, if you do not exactly straight draws this out of the holder. This is for bigger people might be possible but once a smaller person (under 170 cm) attempts to lift the tray from the base - with a child even more difficult - canted this very quickly. We have the shell incl. Base must pry out of the car today entirely because this has not broken away from the base. After much back and forth, we finally succeeded. Something no one needs and is not suitable for everyday use. A pity really a beautiful baby seat but with great weaknesses in everyday use. No purchase recommendation
