Do multi-cookers like the Ninja PossibleCooker actually slow cook well?

This is the most contested point in the data. Specialist-community threads on r/slowcooking and r/Cooking repeatedly note that multi-cookers tend to run hotter and faster than a traditional crock pot on the low setting, so long 8-hour recipes can finish early or overcook. They're praised for searing and one-pot convenience, but if pure slow cooking is your priority, a dedicated crock is the safer pick.
