Where these two actually differ

  • We flag Polymer band composition and residual monomers and Bacterial growth in sealed band-case junction on the Amazfit and not on the Fitbit.
  • We flag Azo dyes and colorant safety and Heavy metal content in dyes or pigments on the Fitbit and not on the Amazfit.
  • The Amazfit is Titanium alloy case, polymer band where the Fitbit is Elastomer/silicone band, which is most of the difference in these two grades.
  • These two are level, close enough that price and fit should decide it rather than our grade.

Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
