K'Nex Marble Run - 3 modelbouwset (gemotoriseerd), 350+ stuks, STEM educatief speelgoed voor kinderen, jongens en meisjes vanaf 3 jaar, bouwspeelgoed voor kinderen voor jonge kinderen.

Bought for my 9 yr old nephew and he loves this. Almost educational too in how it gets him thinking and creating!

The print instructions aren't bad by any means, but it was a little challenging to figure out which rod to use where given they're all the same color.There was a small piece of paper tucked in the book that provides a link for troubleshooting. I took a look-it sends you to a video that does a good overview of building the model and making it work well.More importantly, in the video description there's another link for updated web instructions that include extra letters and numbers that really spell out what to use where in each step.I had the instructions up on my laptop and printed out the slip sheet to organize the different rods-worked like a charm! Great build, lots of fun, and a good amount of support material-would definitely recommend to anyone young or old that likes to build or tinker!

My grandson used this along with his other sets and had hours of fun.

This was purchased for my grandson and he is having a blast putting it together and playing with it.

Cadeau offert à mon petit-fils. Très content, il aime beaucoup ce jeu même avec l'aide de ses parents ils n'ont pas réussis à l'assembler correctement pour que ça fonctionne. Malgré les instructions pas très claires et des vidéos. C'est désolant car très cher.
