"I agree with the previous reviewer in that the new train wheels without metal axle are quite rubbish. I think their advantage is simply that they are much easier for younger kids to put together. But then the new couplers (non-magnetic) are a fiddle so that negates the above. Otherwise, this set is quite fun. It looks awesome in my opinion and provides a decent amount of playability. Pretty straight-forward to build so will suit a diverse range of builders. I love trains so this had to be added to my collection, but I should warn that it requires quite a big mod to motorise it. This was also the first of the hidden side sets that i have built and so far I like the theme. The overall feel of the theme is well designed and the characters are fantastic. The augmented reality app is pretty cool, and although it became boring for me quite quickly I think it would entertain a younger audience well."
