Our 4-year-old son got this set for Christmas. We chose this set because we have different ways to build vehicles approached. In addition, we had been looking for something, where our son can practice his fine motor skills a bit. The set is absolutely sufficient to start with. For our son however, is still a bit difficult to build things all by yourself, because the parts sometimes difficult eineinandergreifen and he sure does not yet have the strength. But it also makes us adults fun to help him. Conclusion: recommendable.
