Review: Great toy, a lot of fun! - I purchased this for my nephews, and it has been a massive hit! From the moment they opened the box, they were completely captivated by the endless possibilities for building and creating. The magnets are strong and sturdy, making it easy for little hands to assemble and disassemble the pieces without frustration. I love how this set encourages creativity and problem-solving while also teaching basic STEM concepts in such a fun and engaging way. My nephews have built everything from simple shapes to complex structures, and their excitement never fades! As a bonus, the included guidebook provides great inspiration for new designs, but the kids love to freestyle their own creations too. It’s a perfect blend of fun and education, and I feel great knowing it’s helping them develop important skills like spatial awareness and teamwork. The quality is fantastic—durable, safe, and well-made. It’s also compact enough to store easily, and the storage bag is a thoughtful addition for keeping everything organized. I would highly recommend this to any parent, teacher, or caregiver looking for a creative, hands-on activity for kids. Whether for playtime, homeschooling, or just some screen-free entertainment, this set is worth every penny!

## Questions & Answers

**Q: Can anyone post a video of the marble rolling?**
A: There is a video posted on the seller page.  It is located on the bottom left-hand side of the additional photo column.

**Q: Can you connect this magnetic run with the makeway marble run?**
A: I do not have the Makeway, but have several other systems. This marble run uses the fridge or metal surface it is attached to in order to hold the marble - as opposed to systems like Fridgits that completely support the marble away from the surface it’s attached to. It might be possible to create a transition from a system like this to another, but it would be difficult to have this system second. The marble would likely fall away as it only supports the marble from underneath on the outside, but supports the marble from the side on the fridge side.

**Q: Can you buy more sets to enlarge the experience?**
A: I don't know if they sell individual sets of extra pieces,  but you could buy 2 or more of this set and I'm sure it would  be even more fun.

**Q: Will this cause scratches on the fridge?**
A: No it won't cause scratches

### ⭐⭐⭐⭐⭐ Endless fun
*by A***J on February 3, 2026*

So much fun! Got this for my little brother. We had a great time building all sorts of tracks. They are easy to build and charge with. Just so you know, the tracks do look like they could be metal, but they are plastic. It’s not a bad thing, they work just fine.
