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 Instant Pot.
- We flag Nonstick coating integrity under high heat and Coating flaking or microparticle ingestion on the Instant Pot and not on the Big Boss.
- The Big Boss is borosilicate glass, bare uncoated where the Instant Pot is Stainless steel pot with unspecified nonstick coating on crisping basket, 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 Instant Pot grade, at 42% 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 →
