WE like this set. We end up playing with it and because we are playing with it our 5 and 7 year olds will want to join in. They don't ask for this one though. I think because it is a little more difficult to build something sturdy. The pieces don't come apart easily, it's just that you've got to really engineer something well in order for it to stay put. I believe over time, they may come to like this one more. I don't give it a bad review because nothing is wrong with it. Just maybe a bit too difficult for my 5 and 7 year olds.
