[This review was collected as part of a promotion.] My kids love marble run toys so they were excited to get this toy. This toy is for an older kid since there are so many parts and it is very time consuming to put together. My 10 year old has working on building the marble run for about 4 days after school. It is still not fully assembled but he is still enjoying it. He did complain that some pieces were hard to attach and bent a little. I like that he is able to be creative with this toy and it’s a little bit of a challenge for him.

[This review was collected as part of a promotion.] My kids had so much fun playing with this BUT it was a nightmare to put together. We quickly lost a few pieces so we had to improvise a bit at that point. Overall, it's a really cool toy but I would way the age range of 6+ should be more like 8+.

[This review was collected as part of a promotion.] We were excited to do this marble run because the picture on the box makes it seem pretty cool. Unfortunately, the instruction manual is hilariously impossible to read. The pictures and numbers / callouts are so incredibly tiny to read. Most of it is also printed on the grey base so you're trying to read black font on a grey base that is font size 4 (maybe smaller). You can try to replicate the image on the cover or just make your own design by DIY. The pieces are easy to put together so that's one nice thing about it.

Absolutely excruciating to assemble, but once you figure it out, it’s super fun. Took me (a 30+ auntie) more than two hours to put together track option 3. Many frustrating moments. My hands are calloused. I’m exhausted. But once it’s done, it’s pretty cool.

Whole the set is nicely made and should be fun, the instructions are RIDICULOUSLY small. It is near impossible to see where the pieces go and being off by one space can throw off the whole set.

Hard to build. I took photos of the grid locations if it helps.

If you can this set built it would be so much fun. II didn’t get this set built as it’s too complicated

This was too much for my 9 YO to put together alone, we worked for about 2 hours to set it up, not particularly fun to do. It’s pretty neat once together, we raced the marbles about a dozen times then he was over it.
