The Classic Wheelo Junior is a toy in which the user tries to keep the disc on the wire tracks. A magnetic field helps keep the disk on the tracks.
The Adjustable Wheelo Junior has the same principle but adds a twist; the current that flows through the metal tracks can be changed by the user!!! With this manual control, the magnetic field of the wires can be altered and true magnetic power can be released!
The originial Wheelo Junior was already very affordable. This version costs a bit more but is still very reasonable...especially when you consider the magnetic power that comes with the package!
Construction wise, the toy cannot be taken apart. All pieces are sturdy except for the metal tracks, which can be bent and bent back into shape. Because it cannot be taken apart, it is very durable.
