Not kid friendly. It has all the items as given, ideas can be access from its website. but the basic thing isthat it is for kids, so it should be kid friendly. connecting the parts is a herculean task, and items being tiny cannot be done by kids. if connectors were provided then i can give more stars. As of now not worth it for kids as better kits are available with ease of assembly.
Really good product. Fun for my son. He loves the idea of being able to connect and put the switches on and off and see the hard work in action. Interesting concept to give kids an introduction to how electronics work. Would recommend this for others. But if your child is younger be ready to do all the hard work for him/her to understand it. Got the videos and color instructions seperately on contacting and it was superb.
