My 10yo choose this product as his birthday gift. It took him 4 to 6 hours to build the most complex design out of provided 6 designs. While building this structure is fun and its not too easy since provided guide book is not well directional. Once build we found out that some of parts does not stay solid and moves with provided heavy ball. Many times ball drop out and structure parts moves. He played just for 10 min and gave up. I advise that do not spend money on this as this item is not fun looking.

I grew up with Marble Works- which is a great marble run for kids, but a bit lacking for those of us that want to do more intricate builds. Gravitrax is exactly what I wanted from a marble run- it has a variety of different pieces, is very customizable, and it has a number of premade tracks to get you started before building your own. I'll definitely be adding more sets to my collection in the future.

Although the box did not have the package wrap on it, all of the pieces were untouched and still have the "new" feel to them. Every single bit of this is fun. Thank you so much for having the at such a low price. If it wasn't for that, I never would have gotten it.
