The seat is easy to operate, quite easy to use the fishing protection (up to 3 years). Also at the Isofix system of the car he is quickly installed, allowing a mounting and dismounting (if necessary) fairly straightforward. Basically, a plus of Isofix seats: He can ride without small passenger without having yet to fix it separately. Only the fishing protection must then be stowed somewhere in the car (eg. As in the footwell in front of the seat).
Advisable is a pad, so you do not scratch the upholstery with the Isofix unit. These documents cost only a few euros and bring mostly a few practical pockets.
Negative me only the weight is noticed with about 10 kg. It's exhausting not only during installation and removal, but consumed in doubt unnecessary fuel. There are other child seats in this class that perform the ADAC test is also good, but a few kilos lighter.
We are so far still very satisfied - hence four stars.
