Where these two actually differ
- We flag Bacterial growth / skin irritation from band material, Nickel leaching from stainless steel hardware and Elastomer degradation and microparticle shedding on the Fitbit and not on the Mophie.
- We flag Microplastics from case degradation on the Mophie and not on the Fitbit.
- The Fitbit is Elastomer band, stainless steel case where the Mophie is Plastic housing, 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 →
