Bought this for my nearly 3 year old son for Christmas.
The castle itself is a good size and sturdy enough, but the blue turrets are only placed on the top, and therefore keep getting knocked off very easily.
Likewise with the poles and flags - these merely sit in the hole and keep falling off. The drawbridge (which you can lower up and down) snapped within a couple of days, but think that was perhaps my one year old! However, it could be more sturdy.
All-in-all, my son does play with it and obviously enjoys it - it's just frustrating for the parents, having to keep on putting on these turrets. My husband is going to glue them in place!
