About Basic Fun KNEX Marble Coaster Run with Motor Set
62% appreciated the easy assembly process, but 38% found it confusing
The assembly process was extremely frustrating and challenging due to the lack of labeling on the rods in the instructions.
62% found the components to be durable and long-lasting, but 38% experienced breakage
I had trouble figuring out how to make all the marble run aspects work perfectly and had to use some fancy creative pieces.
The track connectors are made of softer plastic and easily pull apart. Sometimes, the connectors don't have a strong connection, causing the track to pivot or pop off when attaching the next segment.
I have been using it for two months and have started over at least 3 times.
I have built 2 other Knex sets before and never enjoyed it, but at least they worked. However, this product is total garbage.
61% appreciated the challenging yet fun difficulty level, while 39% found it too easy
It becomes increasingly difficult to understand how the track should be supported.
61% praised the creative track design, while 39% found it too repetitive
I would love for KNEX to turn this into a line like their micro coasters. It would be cool to collect and combine into a giant marble coaster run or make a marble coaster run amusement park.
It took me 7 hours to make the marble run and I had to use creative pieces and make my own rules. Although I couldn't figure out how to make all the aspects work perfectly, it is still fun.
