Where these two actually differ
- We flag Polycarbonate (BPA) leaching, Waterproof coating composition (unspecified), Off-gassing from sealed polymers and Gasket/seal degradation over time on the Zarges and not on the Zarges.
- We flag Aluminum corrosion and leaching and Bacterial or mold growth in seal on the Zarges and not on the Zarges.
- The Zarges is Aluminum frame, polycarbonate/ABS body, waterproof sealing coating where the Zarges is Aluminum with rubber gasket/hinges, 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 Zarges grade, at 45% confidence against 78%, because it discloses less.
