I have a 13 year old boy with an engineering mind who spent his whole life putting this together after opening it on Christmas morning. It must have taken me 4-5 hours to assemble. He found the instructions clear and used wax and sandpaper to fine tune the parts. At the end of the night he could easily spin all the balls in this cool parkour. He decided he could attach a motor tomorrow. Mom for the win! I will definitely be buying more of these sets from ROKR in the future!
