The bad vehicles have already been described several times. There are probably at least 2 different motors. The latest, with a stop mechanism after mounting are really weak. Moreover, the mechanism does not work reliably, so that a child 2-3 years so that has problems. With an extra-selling black F1 racer, however, the dwarf gets along well. The enclosed cars create about one and a quarter laps (but leave more and more after), the black F1 racer around two (also leaves something to, but less) and the old racer from the 1980s (beach buggy) is about 3 rounds while although he probably already has some kilometers under his belt (with laanger break since the 80s). However, it works only with stiffening of the route. Stability is namely completely neglected. One has a woberndes and wobbling Kunstoffgebilde right. The heavier and faster beach buggy deformed the whole so much that he regularly flies out without Sodnermassnahmen. Va stunts, uphill rides, water rides, combinations like overtaking Jumps with Matchbox cars (which have become much worse ...) are no longer practicable (to light weight and small forces of the vehicles). In addition, the web pieces do not always fit well together, are sometimes very loosely (tape to plug connection necessary) and generally make a very different impression. The certainly do not come from a "ribbon". After the connection works with the old railway parts, especially the old 180 ° turn compared to the new "Glump" is unbeatable. Conclusion: You can use the thing but the disappointment is clear. It will be absolutely hinzugekauft nothing. Would not buy again. Since the low price does not help. Better twice as expensive and durable, then you buy just in small steps and can look forward to extensions. Darda there are no longer practical.
