The KitchenAid KCO255 is a premium dual-convection countertop oven with a built-in temperature probe, delivering fast, precise cooking and a rich set of digital features.

The Cosori 11-in-1 Air Fryer Oven offers a generous 13-quart capacity with eleven cooking functions and smart Bluetooth temperature monitoring. Its timer cannot be paused when the door opens and its sizable footprint can be challenging for compact kitchens. Ideal for families and meal-preppers seeking versatile, connected cooking.
