The whole family, mom dad and 4-year-old child are excited. And easy it is to build fabulous designs for the child, he learns very quickly different towers, roofs, staircases autonomously build. I think the game we will not be so tired quickly, I expect many years of fun. Can perhaps seem expensive, but the parts are accurately calibrated and impregnated so that they do not lose the tactile sensation of wood (such as the case with painted wooden blocks is).
