We had the seat, after a letdown with the Kiwy qfix (see review here) when tested with friends and loved it. So Amazon ordered a Cybex, which was also, as always, delivered very quickly. The seat fits perfectly in a Touran, is easy to use and very good "fit" for the daughter. Technically and visually so well. BUT: In the first ride without a child, I noticed an annoying crackling from behind. I do not know where that came from, probably from the trunk. When the daughter then sat in the seat, it crackled frequently. And you also complained that there are cracks. I have then considered the seat and everywhere once pressed- and at the two head protectors I found it. Once these have been only lightly pressed / touched, crackled the Styrofoam. Apparently a manufacturing defect (bad bonded / connected to the outer shell) so I thought. And an exchange seat at Amazon purchases. Unfortunately, this is not so strong, but disturbing crackling. The test in the store (babyone) in Nuremberg was then that these seats had all the same mistake. The Cybex Solution X.fix 2 incidentally not! In babyone I was then able to find and bought the Chicco Oasys 2/3 spot on offer (sorry amazon). This seat is finally perfect.
