bought this when my daughter was around 19mths. for the last 4 mths she has pretty much asked for "tunnel train" every evening and daddy has to play with it. have added it to the basic Brio set we have. she loves watching the train go through the tunnel. I am amazed how something so simple and relatively inexpensive has transformed the set and her interest/enjoyment in it. and it looks great too and so far no sign of any wear or tear. a great buy am very happy with it and will certainly buy more Bigjigs products to go with the Brio set.
