If the various accessories for this kit, taken separately, are of good quality (especially the mini screwdriver that really works) and that the briefcase itself is quite nice, I find the content limited enough to actually tinker, create assemblies. There are only two small boards with 3 holes chacunes two "peaks" and four screws with nuts. The possible combinations of this set are very few.
Result: except to buy other kits of the same brand to extend the assembly possibilities and therefore enable a creative activity, it is a toy that is quickly get bored.
