Rated 3 out of 5 by Product was difficult to assemble The product is much smaller than we thought. Wa not able to get the lights working correctly. Is very noisy! 01/15/2016
Rated 1 out of 5 by Pieces don't fit together easily. Even with his father and grandfather helping, my grandson wasn't able to get screws to fit. The gift is sitting in the box because my grandson needs help in cleaning parts so they will fit. I love the concept but the parts have extra plastic on them that has to be sanded off before anything fits well. My grandson is thirteen and we were hoping he could learn about motors before he got his own car in a few years. 02/25/2013
Rated 5 out of 5 by Science and Math thinker I got this for my grandson's 11 th birthday. He is opening it this mornng, I know he will enjoy this fasanating toy. He is very interested in anthing mechanical. A real Science and Math kind of kid, this will challenge him...if not he can pass it on to his brother who is now 7 These are bright and engaging kids, I am calling him at 7:30 and will get the final words from him. 11/16/2012
Rated 2 out of 5 by Lots Of Steps This has many steps in the directions. It was also sometimes very confusing. Very tiny screws that were difficult to screw in. Some parts actually broke off prior to building it-poorly made. Some screw holes did not fit the screws and we had to enlarge them. Much more difficult and time consuming than we thought. My 11 yr old would not have been able to do it by himself. 02/27/2013
