Popular But Problematic
The BIGGERFIVE Vigor 2 is one of the best-selling kids fitness trackers on Amazon, with an 8.5/10 rating from Android Police. But our research uncovered issues that temper that enthusiasm.
What Works
- Kid-specific design with fun interface
- Parental controls via app
- IP68 water resistance
- 5-7 day battery life
- Badge/medal motivation system
- Works without app for basic functions
What Doesn't
Accuracy Problems Android Police testing found distances "off by up to half a mile" compared to Apple Watch. For a step counter, that's a significant variance that undermines the core function.
Privacy Concerns BIGGERFIVE is a Chinese brand, and while they offer app connectivity with parental controls, that means data transmission to unknown servers. The brand falls into the "off-brand cheap electronics" category that ReviewMeta found most associated with fake reviews.
Display Issues The screen is notably dim and hard to read in sunlight—problematic for an outdoor activity tracker.
The Verdict
If you're buying two trackers for kids and budget is tight, you could do worse. But the accuracy issues and privacy concerns mean this isn't our recommendation when the Garmin hits $60 on sale.
