What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Cosori Pro II Smart Air Fryer 5.8qt (CP158-AF)
One whitelisted tester, Tom's Guide, gave this model a hands-on review, naming it the Cosori Pro II 5.8-Quart Smart Air Fryer (review SKU CS358-AF). It rated the fryer among the best for browning and crisping, measured 65.3 dB operating noise and a 128°F peak exterior temperature, and roasted a 3-lb chicken in about 40 minutes. It flagged sluggish touch controls and poor, uneven toasting. No other whitelisted outlet hands-on tested this exact Pro II Smart 5.8qt unit. (1 sourced review, 1 lab-tested.)
Praised: Consistently browns and crisps a wide range of foods; the standout at air frying; Easy to use with nonstick dishwasher-safe baskets, plus Wi-Fi/app and Alexa/Google voice control; Contains grease, splatter and smoke; roasted a 3-lb chicken cleanly in about 40 minutes and stayed cool outside (128°F peak).
Flagged: Touch controls are somewhat sluggish to respond versus the Cosori TurboBlaze; Poor, uneven toasting; won't replace a toaster; Real usable capacity is well below the 5.8 qt rating (about a pound of food / a 9-inch-square footprint).
Breville Smart Oven Air Fryer Pro (BOV900BSS)
Two hands-on testers — Good Housekeeping's Kitchen Appliances Lab (backed by four years of daily home use) and Tom's Guide — rate the Breville Smart Oven Air Fryer Pro a versatile, premium countertop oven that excels at baking and roasting and can nearly replace a full-size oven. Both independently flag uneven, slow toasting and air-frying that trails dedicated basket fryers, plus accessories that aren't dishwasher-safe and a large footprint. (2 sourced reviews, 2 lab-tested.)
Praised: Versatile all-in-one (13 functions) that can nearly replace a full-size oven; Excellent baking and roasting — juicy crisp-skinned chicken, golden cakes and cookies; Large capacity handles big batches (up to nine slices of toast).
Flagged: Toasting is uneven and slower than a dedicated toaster; Air frying is weaker than dedicated basket air fryers; Accessories not dishwasher-safe; air-fry basket hard to clean.
