Rated 5 out of 5 by from great for the boy tinkerer I bought this for my 12yr old son. He loves it. He had it built the day after he got it. It's a great tool. As he built it I explained what the parts were & how they worked. I paired the engine with a book on how things work and had him read all about the engine.

Rated 2 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 5 out of 5 by from Great tween gift My 12-year old was unsure about this when I gave it to him. But, after putting it together he found a new love of building & learning new things. The only thing negative about this toy is one of the wires was damaged when we opened the box.
