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 Delonghi.
- We flag PTFE fume inhalation (thermal decomposition), Non-stick coating degradation and ingestion, Plastic off-gassing (housing and non-food-contact parts) and Inadequate temperature control leading to overheating of coating on the Delonghi and not on the Big Boss.
- The Big Boss is borosilicate glass, bare uncoated where the Delonghi is Non-stick coated cooking basket/tray (type unspecified by brand), 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 Delonghi 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 →
