After a few days of use, and about 1000 km of road, we are very satisfied with this seat. The seat is easy to install, Baby also fits very well and sleeps in comfort. The only problem has been to find a solution to its large size (70 cm) when he was only 6 months: the insert infant was too small. So we took out the removable foam insert to put it directly into the seat and the back and the baby's bottom. As baby is properly seated as if he was all limp. I think that the solution does not present any safety issue but a shame that the manufacturer did not intend and documented this kind of difficulty.
