I debated between four stars and five stars, but finally decided on five stars since the final project is so excellent. However, there were a few minor problems. First, the directions are simply not clear, obviously written by somebody for whom English is not a native language. In addition, some of the pictures, such as the circuit board, were not the same as the actual product
I also found that one part, number 44 did not accept screws, and I had to improvise to fix this.
These minor problems aside, I enjoyed building this, and my grandchildren are having fun playing with the robot
