Generally a poorly put together set. The box construction leaves much to be desired as it has a rip apart tab along one side. It is not intended to be kept or used as a storage case as with most previous boxes. There was a part missing in the box I bought and this combined with the poor finish on the flexible plates and the lack of detail for builders in at least one of the models tends to give the set a low mark. There is some innovation in the main motorcycle design which is worth constructing.
