My 12yr old son and I had a blast building this. No missing parts, and works as is should. Happy son, happy momma.

It works your mind

Although it is kind of fun to mess with, it's definitely not worth the money. VERY unclear and VERY minimal instruction booklet, and several missing parts that make it impossible to complete correctly. It does run as designed, but there are parts that will not stay in place and complying off every time you turn it on! The only solution for that would be glue, and we're not going there because then it would be too difficult to take apart. As a whole, I would never order this again and I would also not suggest anyone else order it!

The media could not be loaded. This is for experienced builders. Parts are high quality with none missing but instructions were hard to follow.

I purchased this as a gift for a car but friend. He's loving doing the assembly

Definitely not for novice model builders . My husband loved it.

fun
