Where these two actually differ
- We flag Waterproof coating leachates (non-PFAS), Coating degradation and particle release and Off-gassing from plastic or adhesives on the and not on the Zarges.
- We flag Aluminium leaching (acidic food contact), Surface corrosion and oxidation and Sharp edges and handling injury on the Zarges and not on the .
- The is rigid plastic case with waterproof coating where the Zarges is Aluminium alloy, bare unpainted surface, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the Zarges is the one to buy.
- We are less certain about the grade, at 35% confidence against 78%, 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 →
