Where these two actually differ
- We flag Elastomer contact dermatitis, Elastomer degradation with heat/UV and Bacterial or fungal growth in band material 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 Elastomer band, stainless steel case 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.
- We are less certain about the Fitbit grade, at 45% confidence against 82%, because it discloses less.
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 →
