Marble Run, 133 Pcs Educational Construction Marble Maze Block Toy Set, Marble Run for Kids Ages 6-12, Parent-Child Game and Great Gift for Kids.

The whole family had a blast with this. I originally expected to be disappointed - that the balls would bounce out and not go through all these trick tracks. But that was not the case. The balls always made it to the bottom and we had a ton of fun watching them go through all the tracks. And my kids let their imagination run wild and built lots of their own setups too! They have yet to grow bored of this which is pretty impressive. But young kids will need parents' help putting it together - but that's okay, parents have fun with it too!Just be aware these are a bit smaller than you might expect. The marbles and tracks are smaller than "standard" size. But still works well.

I bought this for my son and he really likes it! The amount of possibilities that could be made with the building blocks are close to infinite due to the big variety of the pieces that are available. The amount of marbles are also quite high and the amount of supports make it quite sturdy if you build it right. It’s easy to build and easy to understand. The colors stand out too.

Very small pieces and they break easily. Difficult to use because they are so small and not sturdy.

My Kindergarten students loved playing with these, but we found that they did not stand up to the daily play of a busy Kindergarten class. We had broken pieces nearly every day, mostly the pink pieces - some that ended up being very sharp. I was disappointed as my students did enjoy these and it was nice to see their creativity and problem solving skills. I will need to replace with something more sturdy. These might be more appropriate for home use with some gentle children.

Just opened package. Pieces are smaller than expected. And the marbles are a bit smaller too and plastic not glass. Kid seems happy works as should. Just some observations.

I really enjoyed building this with my five year old son. It was the right amount of challenging for him. Afterwards it was super fun to run the marbles through. The parts are well made. Definitely would recommend this.

My son & daughter loves it.they always play with it and they make marble runs throughout the week.it's fairly sturdy. I would highly recommend this for anyone with kids whoenjoy putting things together.It's very large so there are always new options of routes to try.
