We really liked the gear construction set from Unika called Unlimited Fantasy. The gears are large, bright, made of elastic plastic, and fasten well to each other. The quality is very good. Our first crafts were snakes that wiggled when they moved and many multi-colored towers. Crafts like this rocket also were very easy to make. You will need two sets or more even for one child; one would not be enough. Children make simple crafts and enjoy manipulating bright details. This set, in my opinion, will be interesting for children aged 3-7 years.
These gears are a version of a popular type of building set. The gears in this one are not rotating on top of some structure – they are the basic building blocks of the set. The gears connect if you interlock the pins, or if you stack them. With these simple connections, you can build different shapes and mosaics.
All the gears have the same shape and size, the only difference is the color. However, there are still many possibilities to build, especially if you have many pieces. The gears can also interlock if you connect them at an angle. Sadly, the possibilities to build a moving toy are very limited, because the gears can’t really move once they connect. There are also no extra pieces or decorations, so the gears are the only things you have to work with.
The gears themselves are rather big, they are safe for the small children to play with. They also can hold together even in a very big craft without falling apart.
