Overview
True Surround Convection moves heated air around the food from multiple directions, so two racks of food cook at once without rotating the pans. The Smart Cook System reads internal temperature through a probe and stops cooking when your target doneness is reached. A dropdown door and touch controls run the ten preset functions.
Buyers get an extra-large countertop oven that replaces several small appliances, with two shelves and a probe that takes the guesswork out of proteins. The footprint and weight are the real drawbacks: it occupies a good share of a counter and is not something to move in and out of a cabinet daily.
Who it's for
A family cooking full meals on two racks at once will use the capacity and the probe often. Someone with a cramped counter or a need to store the oven between uses should look elsewhere, since it is heavy and wide.
Pros and cons
- Two shelves cook two levels at once
- Probe monitors internal doneness
- Ten preset cooking functions
- Six trays included for different foods
- Takes up substantial counter space
- Heavy enough to stay put
- No rotisserie accessory listed
- Cable length fixed at 36 inches
Performance notes
Convection power and rack position decide how evenly food browns, so leaving space around the pans matters more than the preset chosen. The probe governs doneness on meats, shutting the oven down at the target temperature instead of relying on a timer. Two-level cooking works because the fan moves air across both racks, but crowding the trays blocks that flow.
