My five-year-old is Lego Star Wars obsessed, (thanks to my Wii game!) and he was given this set for his birthday. He has only just graduated from Duplo to Lego, so it was a little too difficult for him to build without help, but that is to be expected considering it says 7-12 on the box. For me, however, I found this one easy to build because it is mostly symmetrical. The biggest difficulty was that all the pieces are black and grey.
