Where these two actually differ

  • We flag Silicone degradation or leaching from improper cleaning agents, Bacterial or fungal colonization from inadequate cleaning or storage and Vaginal irritation or allergic response to silicone on the Diva Cup and not on the Flex.
  • We flag Bacterial or fungal contamination, PFAS in manufacturing or coatings and Loss of elasticity and structural failure on the Flex and not on the Diva Cup.
  • The gap is 30 points, wide enough that this is not a close call, and the Diva Cup is the one to buy.

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 →
