What we like and what to keep in mind
What we like
- Motorized Ferris wheel keeps marbles looping on their own
- Batteries are included
- Owners say kids 7 to 10 can build it mostly alone
Keep in mind
- Some kids lose interest once the build is done
- Younger kids need an adult for parts of the build
- Base is about 14 x 10.4 in, so it needs table space
How we reviewed it
What owners say.
- 1 positive
- 2 mixed
Paraphrased from public owner reviews. Each one links to where it was posted.
Their son has spent hours with it, changing the layout and testing how fast the marbles can go; the parent is glad they bought it.
Too hard for a 4-year-old to assemble, but the family has left it running for days and likes the quiet motor and the marble sound.
A 10-year-old built both designs in one go and enjoyed the building most, but tends to lose interest soon after.
