This was bought as a christmas gift for my 2-year old. Given at 10am xmas day, and he was still playing with it at 1pm, leaving me to prepare lunch in peace! It was worth the money just for that... No toy so far has ever received that level of interest and joy from him ("Engine shed!!! daddy engine shed!! daddy!! daddy!! engine shed!! etc), but it is also very sturdy and well made (it easily takes his weight to sit on...), very good quality and for any child who loves all things Thomas and trains, it really is a great gift. It is obviously compatible with many different train sizes (all the standard Brio/Tesco/ikea track) and he is still playing with it constantly now. Recommend it very highly.
