It broke in 2 months. The seatbelt broke, which is one of the most important things for the child's safety. I'm writing this comment so that other parents don't make the same mistake.

We got it just yesterday and the child sat in it immediately and fell asleep almost instantly on two half-hour trips. And that alone satisfies me a lot, as with the egg we had an issue because the child was suffocating (5.5 months old, tall and chubby) and when she got upset she cried so much that we had to stop and pick her up to calm down again. We hope that it will continue like this in the future and that it was not a random event. If needed, I will come back with a comment.
In addition, it is a beautiful seat with nice cushions and sturdy construction, it is heavy (12 kg). It is rotatable and very stable with the isofix. The top tether does not obstruct the rotation because the anchor in our car is exactly behind the back of the car seat and the button that tightens the strap is right at the top of the back of the car seat, so it is easy to loosen and tighten again because you have access from the cabin and not just from the trunk. It has 3 reclining positions in the direction of the car and one in the opposite direction. This is the only negative I found and that's why I gave it 4 stars. It is important for the recline to be there to help the baby sleep and not lean forward. In our case, we removed the extra cushion from the reducer which is probably for babies (like a wedge under the black one). We also removed the black headrest so the child does not lean forward, it has space for the head to lie back. Another reason the star is missing is that the user manual is terrible and you can't figure it out. So empirically the cushions were removed and we do not know what the manufacturer's recommendations are. We assume it also has to do with the child itself and its physical development. To us it seems comfortable, we hope this does not affect its safety. The straps close and open very easily!
