Nothing for beginners, quality with obstacles

We bought the play tower, with the real idea that the building does work.
What we think is missing in the article description, specifying the required additional foundations, anchoring means etc.
Since there is no reference to this, you go first rather "naive" to work. We are experienced handyman and still have a complete week needed to build, as you has to factor two days alone for concrete work.
The wood is as already described by others, sometimes very großastig, several boards were glued by us virtually before assembly, since already existed cracks or strong wooden errors. But for must be said that the low price of the game system, of course, also reflected somewhere.
The assembly instructions was generally ok but could of course, as everywhere, are documented with better drawings.
What is really annoying was the complaint of the slide, which was delivered damaged. It actually lasted 8 days, until the spare slide was delivered. To what extent here the seller, or the trucking companies are involved in the delay is beyond our knowledge. But for a simple delivery lasted too long.
Conclusion: The tower is beautiful, all the parts are, however, the structure is not for beginners.
