We all play with it, our daughter (3), son of our visit (7), my nephew (16). It's great fun again and again to create new tracks, Lego Duplo parts we have enough decent pillars and supports to build it. Only agreed at the beginning of the package contents are not (2 track parts variants in wrong quantity, so in total it was true). By email, we have come into contact with the manufacturers and we received an unbureaucratic assistance (the right parts plus a little extra!) We can recommend the product fully, we will definitely buy another expansion set ;-)
