"My son got this set for Christmas it was his first LEGO technic set he is 7 years old and was able to build a lot of this him self I mainly supervised more so than helped him and helped him only where he found the instructions hard to understand overall we both really enjoyed the set it was a great set to start him off and instructions were clear and well done and it made him so proud to build something like this himself with the pull back bike and pickup truck with fully operational steering I would highly recommend this to LEGO fans"
