Sturdy, reliable 5-point harness, easy adjustment of the strap tension, easy release for adults, incredibly flexible rotation and the ability to recline when the child is sleeping. Also very good ADAC rating of 2.1 (the lower the number towards 1, the better, with a maximum of 5 being the worst). Negatives might be its weight (okay, you won't be putting it in and out every day) and the space it requires to face backward

Very good car seat. We have been using it for almost 12 months now, and our child, who is 4 years old, has never complained. The reclining feature is very useful and seems to be extremely comfortable. It appears to be made of high-quality materials, and in the 3 years we have been using it, it has not shown any signs of wear. The only negative thing I could find is that due to the materials and possibly the color, it gets very hot in the summer, causing our child to sweat a lot.

We have had the seat for almost a year.
Extremely high quality and sturdy, although relatively heavy. The child is easily placed as the seat rotates.
The isofix attaches with difficulty and the child does not sit very comfortably, especially on trips.
Definitely a good choice but not for so much money.

I wish I could upload a photo. As soon as my 7 and a half month old baby falls asleep, his head goes back and forth with every turn and brake, causing him to wake up. If he manages to fall asleep, his head hangs forward like a pendulum. We wanted safety, but what is happening is definitely not comfortable or safe, I doubt it. Such a shame for so much money. It claims to have 6 reclining positions, but the fully reclined position feels like the second position.

Very good, sturdy, practical (it rotates to facilitate the placement of the child) and comfortable seat. On the negative side, its relatively large weight and the space it requires in the car, especially when facing backwards.
