Bought after testing at the show Paris is Fun. Children are delighted with the p'tite beast crawling. The game is not so silly because it learns to see how the cockroach reacts to the shape of the maze. The game is renewed moderately since there is little maze. The batteries take rather a long time, several hours of non-stop play, and are far from expensive. The material is honest quality and looks to age honorably. Note that if your children love the Nanobug, there are also separate toy with circuits in 3D.
Only problem, yes, it makes noise. But hey, that's also why children love. Avoid during evenings after the parents;)
Attention, there are two editions of this game is with a die instead of Nanobug. she really has no play value.
