My sons have a zillion peices of Lego and although these large Lego sets can be a bit on the expensive side, I think they are certainly worth the extra especially if you get a great deal on Amazon. My son had hours of fun creating and dismantling each of the vehicles in this pack. As for my point of view each one was of a good size so that my son was able to actually play with it. It was also very sturdy, which is not always the case with lego sets, so nothing dropped of or went missing whilst being played with. Definatley a good purchase.
