Where these two actually differ
- We flag Thermal shock and fracture and Edge chipping and glass fragments on the Big Boss and not on the Cosori.
- We flag PTFE fume risk (nonstick coating), Nonstick coating degradation over time and Off-gassing or odor on first use on the Cosori and not on the Big Boss.
- The Big Boss is borosilicate glass, bare uncoated where the Cosori is aluminum cooking basket with nonstick coating (unspecified), which is most of the difference in these two grades.
- The gap is 60 points, wide enough that this is not a close call, and the Big Boss is the one to buy.
- We are less certain about the Cosori grade, at 35% confidence against 95%, 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 →
