OK, let's cut straight to the point. This isn't exactly a challenging set, I mean, it's for kids 5 and under. The build is very simple, but what impressed me the most was the durability of the pieces. I bought this set for my cousin in law's 2 yr old boy. It kept him entertained for the whole afternoon. And of course, being a 2 yr old, he didn't exactly treat the pieces with care. And by that I mean, they went flying around the room for most of the day. I was sure that the car at least, was going to crack. At the end of the day, I examined the pieces. Not one crack or dent. I was impressed. I also learned something else that day. I am probably one of the greatest complainers when it comes to the cost of Lego toys. Let's face it, compared to a lot of other toys on the market, it's not cheap. But I also know that just about any other toy on that day would have either cracked, broken or smashed. The lesson - Lego is a very good quality toy, that's why it costs more but you know what? At the end of the day, it's worth it. Keep up the exceptional quality Lego - and if means I have to pay more, then so be it.
