The box contents and experiments look very nice and I'm actually glad that they put an emphasis on the electronic symbols. However, the book lacks proper explanations of why certain things are happening, the interaction between the elements and when they are presented English is so terrible even I have problems understanding what they mean. Overall is not bad but it's such a great introductory pack idea that I would probably splash out another 20 or 30$ to get a better quality one (at least as far as the book is concerned). It would be a good idea to guide your kids first steps and really be there to walk them through rather than chuck the book in their hands and send them away.
