My 3 year old daughter loves to play with. The two characters are perfect for creating short stories and indeed unlike other trains 2 Locomotives t wagon offer many opportunities for fun. And in every way. The train is of good quality, convenient access with these thoughtful, brilliantly adapted to the dimensions (bridges, boats and snag snowmen so seats that can be hard for a kid sometimes). So you're very good in terms of play and inventiveness. In materials, then indeed the train is very light (plastic) and openings may seem fragile. However still no breakage after 1 week of lively game and no complaints.
I put 4 especially for the price changes, I had the chance to have a 7.6, but it fluctuates bcp.
