We offered this toy for Christmas in our little boy of 30 months, which have at it! The tower, with its screw, solid air and good quality plastic (she already was thrown to the ground several times, it is even put it down with his 15kg). However, I am a little disappointed! I think the vehicles are not completely adapted because not enough heavy, so they do not slide down the slope as in TV advertising and even still often blocked at the switches. A metal cart is much better! It would seem that certain things be reviewed. I remain still relatively satisfied with this purchase provided they use other vehicles.
