I bought it for a child of 18 months, a little small for how well get the train and its two cars on track. I was quite pleasantly surprised how he was mesmerized by this big building. For with the box 10506, the volume taken by the circuit is quite impressive. It takes such a lot more places brio train and it also makes more noise.
The whole is very solid, colorful and very good quality. It is also and above all the best quality / weight / price all DUPLO sets. Given the possibilities offered by this set, your child hours before him to use all the possibilities.
