About NATIONAL GEOGRAPHIC Magnetic Marble Run 75-Piece STEM Building Set
Overall Feedback:
85% positive
78% appreciated the easy assembly process, but 22% found it confusing
I am thinking about getting a big set as a present for New Year.
The product comes well-packaged and organized with color instructions and tips for success.
I had difficulty putting some of the pieces together due to their design and had to refer to the instructions for assembly.
Assembly of the marble runs requires precision, otherwise the marbles slip between the tracks and the surface you are working on.
70% found the components to be durable and long-lasting, but 30% experienced breakage
The catapult piece works unstably.
I am disappointed with the product's durability as the previous 3 sections fell apart while assembling a new section.
The plastic used in the marble run is slightly soft and bendable, which is a requirement, but it feels a bit too soft to me.
I advise keeping a yard stick nearby to fish out errant marbles from under the fridge. The marble runs may not be durable enough to contain them.

71% appreciated the challenging yet fun difficulty level, while 29% found it too easy
This product is not suitable for small kids, but teens and even adults will like it.
Assembling the marble run is difficult and time-consuming for anyone under 10-12 years old.
This marble run can be frustrating to set up and enjoy, indicating a high difficulty level for some users.
70% praised the creative track design, while 30% found it too repetitive
Some connections are difficult to attach securely and the flat track pieces tend to pop off the magnet connectors easily if not attached properly.
The magnets were not strong enough and whenever a ball would drop on another section of the track, the track would move from the force of the ball.
Setting up the track for my little ones was tedious as every time a marble went halfway through, it knocked the magnet out of position, causing me to reset everything and make tiny adjustments again.
The track design requires precision assembly and configuration, otherwise the marbles slip between the tracks and whatever surface I am working on.
