Just as the pictures suggest, there are three figures in this set and three vehicles can be built following the pictorial step-by-step instructions in the included booklet. The number of pieces are greatly increased by the small round pieces you can see scattered in the illustrations. There are a few extra pieces too you do not need to the construction vehicles but which can start you think of alternative designs. There are a few specialised pieces, such as the roller and the caterpillar track but most of them are generic enough to facilitate creativity. Some of the pieces, especially the flat ones, need considerable effort to take apart once they have been clicked together. So be prepared to help a smaller child with "deconstruction". The quality of the pieces is satisfying, they seem to be durable and the finishing has the same shine as Lego. The design is excellent. I would recommend this set to anyone with children of 5 or older. Also check out any item of the "Blok Squad" series, such as Mega Bloks Blok Squad Buildable Fire Patrol Station Playset, they are high-quality sets. But beware of Mega Bloks Micro Bloks Scoop-n-Build Bucket Classic, in which their is a great proportion of cheap-looking pieces.
