1st,Very nice gift for Children.Excellent time waster,Brain trainer,Good looking.
2nd.Lightake has uploaded official video to youtube tell you how to assemble it.You can see video in our product page.
3rd,Price is lowest. You can save at least 10 USD compare to any other sellers from China.
Not bad for the price mainly for somebody that wants to have it hands-on but my son was having ball with PC game RollerCoaster Tycoon and I wouldn't swap. For start it is just much easier to hit Save and Exit and not to do cleanup… :-)
