Top complaints
Ninja Air Fryer Pro 4-in-1, 5 Qt
- Loud fan
Wirecutter rated it one of the loudest models it tested, with a constant deep whoosh; Tom's Guide measured 72 dB. Amazon's review summary calls noise feedback mixed, and Walmart 2-star reviewers compare it to a car engine.
- Runs hot / overshoots temperature
Wirecutter found that at a 400°F setting the inside reached 430°F before it settled down. Delicate foods like brussels sprouts can char unless you lower the time and temperature.
Source: Wirecutter - Small basket, no shake reminder or preheat
Tom's Guide lists the limited capacity and the lack of a preheat or turn-food reminder as its downsides. Some Walmart owners say they have to shake it constantly.
Instant Vortex Plus 6-Quart Air Fryer
- Durability and plastic smell (shared reviews)
Amazon's review summary for this listing says multiple customers report it breaking after a year and complain of a plastic smell. The listing shares its ratings with other Instant Vortex 6 qt models, including the ClearCook.
- Built-in preheat
Serious Eats says the roughly four-minute preheat runs again if you add a few minutes after a cycle ends.
Source: Serious Eats - Loud fan
Serious Eats calls it moderately noisy, and Food Network measured the fan at up to 66 dB.
