The game is perfect to him

It does not have the power 4. This game is perfect. Always so fun.
So on this model ... less than 20 euros:
The goal, I think, is to fight against copies of the real power 4 which are much cheaper.
Indeed, if this model is cheaper but functional, plastic is much thinner than previous models.
Besides the pieces are hollow.
This does not presume of his strength I community uses.
But it will, however, be more careful with models of 80-90 years who were still functioning 20 years after purchase.
