(More customer reviews)Christmas eve, with all the dazzle, my soon to be 8 grandson poured out the Pieces and began to construct a crane. I was ready to help, but he enjoyed it all so much that I was just the audience, He worked for about 30 minutes and had his first lever constructed. The pieces snapped together well, the only prolem was some small pieces were difficult to click back off when he discovered they were not in the right spot. That's when we got to help, just a little!
