Summary: We bought this stroller in July 2011 and since then the stroller has closed while our daughter was in even after hearing the "clicking sound" indicating it was locked. Uppababy has since notified all consumers that it will be replacing many of these affected strollers because of this issue.
Summary: Don't misunderstand, the brakes work well but their design and placement are terrible.
Every trip with a stroller involves stairs or curbs. The break levers stick out past the wheels in the back and make it impossible to "hop" down or back-up steps. Bummer.
