Across the different versions of what’s essentially the same model, I noticed that the AF400 features a dial that also doubles as a large push-to-start button—a design detail I like. I also like the rear vents that point upwards.

Both models include digital timers, but it’s worth noting that neither of them uses a true touchscreen interface.

The overall finish quality left something to be desired, with noticeable gaps in areas that should’ve been flush. That said, Ninja’s customer service was excellent—they promptly sent out replacements each time, even though every unit still arrived with some form of defect.

I’ve owned and used the AF500, and it does cook well.
