Easy to use. *by on Reviewed in the United States October 13, 2021* This sequentially passes the ball on top of 3 levers topped with shallow cups. The ball needs to be moving quickly enough and the input needs to be at the correct level but once set up it works very well. The levers need to be reset for each pass. You can use each of the 3 units independently if you want, so this opens a lot of options in the track setup. The effect is excellent and once set up it’s easy to use, easy to reset, and it is reliable in operation. It comes in a box that’s too a little too shallow to store the assembled units. ### ⭐⭐⭐⭐⭐ Would buy again *by on Reviewed in the United States December 28, 2023* This is one of my favorite gravitrax extensions. It is very satisfying and good quality. There are many possible tricks you can do with it! Would recommend and buy again! 🌟 🌟 🌟 🌟 🌟 ## Frequently Bought Together - Ravensburger GraviTrax Transfer Accessory - Engaging Marble Run & STEM Toy | Interactive Track System | Educational Experience | Compatible with All GraviTrax Sets | Ideal Gift for Ages 8+ - Ravensburger Gravitrax Starter Set Marble Run | STEAM Accredited Toy | Ideal for Kids Age 8 & Up | Perfect for Endless Indoor Family Activity | Ranked No.1 Marble Run System in The U.S. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/202806746-ravensburger-gravitrax-transfer-accessory-engaging-marble-run-and-stem-toy](https://www.desertcart.at/products/202806746-ravensburger-gravitrax-transfer-accessory-engaging-marble-run-and-stem-toy) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-18*
