I have for Christmas gift firefighters my son (6). Built she has my sister (thinking it was too complicated, but it is not apparently was): D After about 30 min. they had also managed. I then tricked batteries for the alarm and finished. My son immediately busy. And 5 days later still does: D I'm actually more of Lego fan but at Playmobil really like it a lot as it is stable. I have ordered the associated fire department fire truck. Also very good! Can only recommend the station.
