Where these two actually differ
- We flag Unspecified resin additives and plasticizers, Azo dyes or heavy metal pigments in colorants, Formaldehyde or formaldehyde releasers in curing agents and Skin irritation or allergic contact dermatitis on the Amazfit and not on the Amazfit.
- We flag Polymer band composition and residual monomers and Bacterial growth in sealed band-case junction on the Amazfit and not on the Amazfit.
- The Amazfit is Resin band (unspecified resin type) where the Amazfit is Titanium alloy case, polymer 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 →
