After my daughter but was too tight with 10 of bucket seat we bought these increases. Processing, stability as already from the other reviewers noticed properly. Unfortunately, the booster seat by the protruding "ears" of the belt guide is extremely broad. It has thus even less space to time to sit as an adult in between than with a full bucket seat. In sum, the seat is naturally small and can sometimes disappear in the trunk to be killed. For whom the booster seat is sufficient (not for small children) is certainly a good choice.
