The success of Geomag is well established. Children love these magnetic rods that allow many buildings and develop their imagination (and gives you the way a few hours of tranquility). The principle of this variation "Mechanics" is to allow children to experiment further the properties of attraction / repulsion magnetic field by building more or less precise constructions that create the conditions for an autonomous movement (with the inevitable small pulse). So here the idea is good, the realization is a little cheap and the parts far too fragile, clipping the pins being particularly for (a friend of my little blond head broke two from the opening of the box). It would be sensible to add to it at least a few alternative media, failing to produce a solid toy. These new bars, somewhat longer than conventional, are becoming too few to justify such a high price that should be divided by two (50 euros at the time of this writing).
