This is a great starter set for kids moving on from Duplo. My almost 4 year old loves this set. While I, his father did, all the building, my son helped me sort all the colours beforehand. After only 4 weeks, he can now take the vehicle roofs on and off without assistance and put the minifig firemans air tank and mask on. Only $30 in Australia, with 5 minifigs, allows lots of imaginative playtime for young kids.
