75% appreciated the easy assembly process, but 25% found it confusing
It is challenging for a young child to assemble the marble run as the colors are different from the instructions.
The design instructions are not child friendly, making it difficult for children to assemble. It requires adult assembly.
It took me 3 hours to assemble and the instructions were not good enough. I had to figure it out after much trial and error.
I was not able to assemble the product as the assembly booklet was poorly written. Additionally, one of the main pieces was made backwards. After struggling for 3 hours, I gave up and threw it away.

75% liked the high-quality marbles, but 25% experienced chipping issues
The marble set provides bigger hollow plastic balls instead of glass.
I had to make minor modifications to work around missing parts due to the lacking quality control on the packaging.
The marbles provided with the marble run are very lightweight and made of plastic. Real marbles are suggested for most designs.
67% praised the creative track design, while 33% found it too repetitive
I really like this set. The chunking pieces are suitable for both older and younger kids. I also like that duplos work with this set and we can build various tracks. It was easy to assemble and manipulate the pieces.
I think marbles would run the track faster, but I couldn't find any.
I have complained that the track design of the marble-run is not aligned properly, causing the marble to stop. Aligning the track results in the whole thing falling apart.
