Carrycot on the chassis was great, seat unit in the parent facing position was a tragedy because of the center of gravity. Facing forward, no such problem.
Otherwise it's a pretty heavy chassis, so not really for any train/bus travel that isn't low floored. Especially with a heavier child.
German quality, solid materials, technical design thought out to the last screw. It can withstand terrain as well as city. It can easily serve at least 3 children in a row.
A superb stroller, like new after 2 children. A tank that has driven everywhere. Just a little heavier.
