We gave this castle 5järigen our son for Christmas. The construction proved to be extremely difficult and protracted: he devoured each 3 hours at 2 mornings. Also we did not understand right away how to assemble this castle right, for a while we were even convinced us would some wall parts are missing ... the tower we had to complete completion again build out each other, as two major ticks (for stable run Grid running) we overlooked in this plethora of small parts were ... Exasperated, we continued until the next day. Now the castle is finally !!! All parts are installed, everything worked out. The castle is now extremely stable and is absolutely free of stress, they can move well from one corner to the other. The overall quality is amazing oppressive, and amaze all the functional possibilities of the building and inspire us and our son again and again! On Angang patience and perseverance is needed - without question, but after that the game is huge! It is worth it!
