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.
Breville Smart Oven Air Fryer Pro
- Very expensive
Wirecutter calls it very expensive and says a cheaper Cuisinart gets similar results more slowly. Value for money is mixed on Amazon, with some owners saying it isn't worth the high price.
- Durability: shattered glass, failed elements
Durability is a negative aspect in Amazon's review summary (413 mentions), citing glass doors shattering and heating elements breaking.
- Uneven toast, hot exterior, loud fan
Wirecutter, Serious Eats and Tom's Guide all found it toasts less evenly than the best options. Tom's Guide notes the exterior gets hot, and Wirecutter calls the super-convection fan loud.
