Loved all the possible ways to set up this marble run! Marbles are great and they look so cool in the clear tracks. Had to order more baskets to make it easier to load different runs. Totally worth it!
Awesome additions

I ordered this add-on for my son. He was very excited to see that his marble run has extra "things"(as he calls them) for his marble track. They were exactly what was described for the product, and he loves them. They are very sturdy, can be cleaned easily, and fit with no problems.
LOOKS GREAT

So Much Potential

I was so excited to get these and add to our existing Marble Genius set. The "Y Joints" are awesome, smooth with a great mechanism for shifting balls smoothly from one side to another without flaw. Great piece that adds a lot to our ball run possibilities.
The loop-de-loop piece is also amazing. My kids didn't think it would work to turn the ball upside down. But it, does with ease, every single time. And it's color is different than any other piece in the sets or expansion so it really sounds out.
The problem we had was with the open track pieces. The configurations are so cool and add a lot to the visibility of the track. We have found they slow down the momentum of the marble, which is okay really. But with the green figure eight piece the marbles get STUCK EVERY TIME at the end and won't go through the opening. So sad.
