Extra Pieces for More Fun!
I received another vendor's marble set with chutes and the risers. This product works seamlessly with the product I already had. We have 5 grandchildren ranging from 5 years old to under 1. The 4 older grandchildren LOVE when I build a structure. The oldest is now doing more of the building. I not only purchased this set, but also purchased another set that had more base items (to build the structure upon). I can't wait to build again with all these new pieces, which will allow the overall structure to be shorter--which is perfect for the age of my grands! The plastic is sturdy and the pieces fit tightly with what I already had. I suspect I'll be buying more items from this company as our structures grow!!!!

Not compatible with JOYIN
I bought these thinking I could use them for the Joyin Marble Run but unfortunately the tubes were way too big !! I just wished toys were more universal (with toddlers of course pieces always fo missing) but other than that it seems nice to buy their entire brand and build it at home.

Completes my original set of Marble Genius
The original Marble Genius set was always falling over because there were not enough bases. An adult had to hold put the structure. This set lets two children build together.

Super Fun!
This was a great addition to the basic set. My 7 year old really enjoys extending her marble run with this new component. So far, it has worked flawlessly. We watched the company's online video on their app for help with assembly and it was really easy

My kids have a marble run so I bought the suggested extra parts as seen here. But they are not compatible at all. Very disappointed.
