Review: Cool gift - Bought as a gift, the child loved it and really enjoyed building and playing with it. Fab set for inquisitive minds. Needed a little help from an adult
Review: fantastic - I bought this for my daughter and she had great satisfaction putting it together, the instructions were easy to understand and simple .The mini solar panel works perfectly and the speed of the solar system is not too slow or too fast .It doesn't make too much sound while operating. Overall I think this product is amazing and productive.
