Review on Marble Genius Pipes Sphere Attachment by Mark Raj

Revainrating 2 out of 5

Difficult to understand even for an adult

Our kids love their marble maze and we thought this would be a nice addition - we were wrong! The tubes are fragile and can be easily crushed without adult supervision. The connection between tubes and balls is difficult to make properly. Once the pipes become part of a big maze, things get really unstable due to the tension and pull of the pipes. The hose must be recycled for this product to work.

Pros
  • Best in its niche
Cons
  • Periodicity
