Ravensburger GraviTrax Zipline Accessory - Marble Run, STEM and Construction Toy For Kids Age 8 Years and Up

Perfect activity for a Clever kid. He loves doing construction activities and particially thinks that light up.

The moving ball hits the top ball on the zip wire which in turn goes down and hits another already pre-placed ball at bottom.My son had great fun using this piece. Great way to change the colour of the ball and make the flow of the ball look really interesting. My 10 year old found this easy to assemble and overall it’s generally quite reliable and rarely goes wrong.

I purchased the Ravensburger GraviTrax Zipline Add On Extension Accessory for my two young boys, and it has been a delightful addition to our GraviTrax collection. This Zipline accessory adds a new dimension of excitement and creativity to the marble run experience.The build quality is excellent, reflecting Ravensburger’s usual high standards. The pieces fit together seamlessly, and the zipline mechanism operates smoothly once properly set up. My boys were thrilled to see the marbles zip across from one tower to another, adding an extra layer of dynamism to their marble run designs.However, it is worth noting that adult supervision is necessary, particularly for younger children. The setup can be a bit complex, requiring patience and a keen eye to ensure the zipline is correctly aligned and tensioned. Additionally, the marbles can sometimes get stuck or derail if the zipline is not perfectly balanced.Despite these minor challenges, the Ravensburger GraviTrax Zipline Add On has significantly enhanced our marble run adventures. It encourages problem-solving, engineering skills, and endless creativity. I highly recommend this product to anyone looking to expand their GraviTrax setup, but do keep in mind that a bit of parental involvement will ensure the best experience for the children.Overall, a fantastic purchase that has provided hours of fun and learning for my boys. Five stars for sure!

This was an addition to our well loved gravity track and customer service was great sending us a missing piece so fast. My kids, 10 and 6 are super happy! They have played with the gravity tracks well over a year and they do not get tired as there are many challenging and entertaining options to try. It is more like the oldest brother takes the lead and little one assists and gives input on construction, as it is a game I would day 7/8 plus. Really please with customer service. It is an expensive toy but it is of quality and well designed.

Does NOT require batteries, despite what the Amazon spec says!Excellent product.

Bought as part of a present for 10 year old grandson, who was very pleased, and couldn't wait to assemble it.
