Where these two actually differ
- We flag Nonstick coating integrity and leaching, PTFE fume inhalation (conditional) and Coating wear and microparticle release on the Cosori and not on the Ninja.
- We flag Thermal fracture or stress in glass cooking vessel, Plastic housing off-gassing (VOCs and formaldehyde) and Electrical hazard or heating element degradation on the Ninja and not on the Cosori.
- The Cosori is stainless steel body, nonstick interior coating (unspecified type) where the Ninja is Glass cooking vessel with stainless steel and plastic components, 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 Ninja is the one to buy.
