Review on Perplexus Epic: Conquer the Challenge of Interactive Obstacles! by Demetrius Young

Bought a couple of these to confuse all the males in the family for Christmas. It was great, they were a hit. It was actually a time when all cell phones were unknowingly put away as everyone stared at the puzzle. I am addicted! I noticed the other day that the ball is starting to change. It looks rusty. The shiny (chrome?) finish wears off and the ball doesn't roll as smoothly as it used to. I'm not sure if that affects gameplay. I'm not too concerned as the ball is sealed. It's frustrating to think that there might be other limitations in the overall quality of the product. The overall difficulty of the puzzle is definitely four stars, but I'm downgrading it for now due to the quality I'm experiencing.
