The Quad is actually made quite nice and runs it quite fast. The exercise house is a nice idea - one can thus still "open day at the fire department" replay => enthusiasm and anticipation for the child! The pumps from functioning at all. If you build the whole in accordance with instructions and pumps, is virtually no water from the hose. There are too many joints that do not really fit tightly - so there is no pressure can build up. After mehrmahligem Try the connectors "Swallowed", ie not at all keep together and more easily slide apart. Then it is no longer possible to connect the water-filled syringe directly to the pump => only disappointment in the child.
