Who has ever wondered why there are no pictures of the front of the set, which was said: Because she's so ugly and inconsistent, one can hardly believe it. The set is of course quite clearly intended to make it to record from the one shown side, sure. But so far, Playmobil had yet taken to ensure that the sets are also around quite respectable. The here is not so. The secret room is on the other side considered not so secret anymore, but sticks out like a shapeless white square from the otherwise dark rock. Each agent of the other side would see immediately ... In addition, to open due to the possibility of a loud rock parts, the whole construction is quite shaky. As nice as the upper floor with its large windows is transparent, that's all very delicate and thin-walled. When you build you more afraid something to break, because you certainly must exert pressure in the right places during mating. It says to eyes and through. To say something nice: Interesting are the 3 electronic components in the set. In particular, the LED display stands out here, as well as the alarm system works really well, but is fairly quiet, but easy on the ears of parents. All in all, I was a bit disappointed because the set is as good as not expandable with other System X sets of Playmobil. The basic construction of large parts does not allow other construction in principle. So if for example, thinks: oh, a fine stone staircase! I would have liked to build on my existing harbor fortress, will be disappointed. Almost nothing is compatible with other sets. The rocks have typical holes for plants or other rock parts. And I so much equipped Playmobil sets still pending with vegetation.
The rhyming conclusion is: Although the set uses the system X, but compatible becomes almost nothing.
