The instructions were easy to follow and even my seven-year-old was able to help create the track system. He received this from his grandparents as a Christmas gift and while it was a little too advanced for him to put together, he did enjoy helping out with the easy pieces. Once complete he was raving at how much fun it was to watch the balls in action. He hasn't stopped talking about it to his friends. ### ⭐⭐⭐⭐ Super Fit, Fair Quality Materials, Mediocre Insructions *by M***S on December 18, 2021* Assembly is reasonably challenging. Fully and properly assembled it works wonderfully. Be certain to have some gel type super glue on hand. You WILL need it! Unless you have small fingers you will need a pair of long, delicate needle-nosed pliers. I'm very comfortable with pictorial instructions and these were fair. The background illustrations were too faint in my opinion however and some steps were out of order with testing omitted. The long twisting return ramp path works perfectly with a single ball but will shift due to the weight of multiple balls in the event of a clog. Some things I learned: 1) The ramp/rail assemblies at the beginning should be glued together with gel super glue. Glue the brackets to the ramps from beneath. The "ribcage" section does not need to be glued. 2) After step 9 skip ahead to page 22 (step 23) and glue on the rails. Glue everything except parts A29 and do no press parts A29 into the ramp--only the rails. 3) In step 13 be certain that the clear plastic "keys" are hanging down to the right as viewed from the "ROKR" side of the assembly. When the assembly is complete test it by putting a ball in each hole with the "key" dangling below. Use a ball point or similar to push the key from the short end opening and the balls should fall. 4) Secure the ends of each wheel assembly with some glue. 4) Before you mount anything on the base skip ahead to the final step and add the feet and identification plate. If you don't add the feet the base won't be level and testing is nearly impossible. 5) Periodically test the ramp during with a ball during step 23. The sections must be FULLY pressed down onto their mounting tabs! This is not particularly and they don't always like to stay that way. Once you've installed the "ribcage" section, test thoroughly. When you're pleased put a dot of glue on the top of each mounting tab where it comes through the ramp. Set aside for a while and take a breather. --- ## 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.sg/products/330379123-lga01](https://www.desertcart.sg/products/330379123-lga01) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-05-21*
