Where these two actually differ
- We flag Vulcanization residues and accelerators and Degradation products from sweat and heat on the Fitbit and not on the X-Doria.
- We flag Nickel leaching from stainless steel on the X-Doria and not on the Fitbit.
- The Fitbit is rubber strap where the X-Doria is Stainless steel, magnetic closure, 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, which covers 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 →
