Unfortunately here also insufficient Qulaität in durability, because after a few (tentative) Aufziehvorgängen the engine is no longer useful. Sorry, no quality more as before, where the engines were almost indestructible. What good is a really great track, if it seems to be no (!) Useful cars or engines are more (s. Also many other reviews from other buyers across all newer Darda cars). Is it possible to train well to throw away without cars :-(
