My son loves this simple model becaufe:
* The ring above is fun to shake,
* The rings légéers and its semi-rigid plastic, which allows to launch,
* He loves me or rolling them around in top,
* He learns to follow suit them, with the challenge of velontairement unstable base ...
* It teaches color and sizes,
* He likes to see the float and try to sink them,
* He loves the tapper against each other,
* The size is suitable for those little hands.
In short a great success
