Definitely not an easy build for 8 - 12 years old. Wiring not up to par with other models.

I've removed some stars from my previous review because of several key issues. These issues will not adversely effect an experienced Arduino builder but provide many pitfalls for beginners. The overall instructions leave something to be desired. Wiring diagram graphics are hard to see and interpret. Instead of providing solid connectors for the motors they must be loosely clamped in a block that is not sturdy. Many components such as the photoelectric eyes are not in one piece and no instruction is provided on how to wire them together properly. The wires on the motors are too small of gauge and soldered in a flimsy manner so that I had to repair and replace them so they wouldn't fall off. I found critical hardware missing and had to substitute my own or go without. In short I cannot recommend this kit. Better to spend a bit more, especially if a child is involved.
