Where these two actually differ
- 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 Tefal.
- We flag PTFE coating decomposition and fume release, Coating degradation and microparticle shedding, Aluminum leaching (housing/basket metal) and Polymer off-gassing from housing plastics on the Tefal and not on the Ninja.
- The Ninja is Glass cooking vessel with stainless steel and plastic components where the Tefal is PTFE (Teflon) nonstick coating on cooking surface, which is most of the difference in these two grades.
- The gap is 55 points, wide enough that this is not a close call, and the Ninja is the one to buy.
