Focus on pure convection capacity, wattage, and the type of heating element (fan‑assisted vs. true convection). Check the vent fan’s CFM rating to ensure it can clear steam and odors effectively. Also verify installation dimensions and whether the unit includes a built‑in lighting system for better stovetop visibility.

The BLACK+DECKER unit combines microwave, air‑fry, and convection functions, offering flexibility but often with lower convection power than a stand‑alone oven. Its 300 CFM vent is strong, yet the convection fan is shared with microwave components, which can limit temperature precision. For pure baking and roasting, a dedicated convection oven typically provides more consistent heat distribution.

A larger cavity, like the 1.9 cu ft. offered by ThermoMate, lets you cook bigger dishes and multiple trays at once, improving efficiency for families. However, bigger units may require more clearance space and can be heavier to install. Match capacity to your typical cooking needs and kitchen layout to avoid wasted space.

Both have similar capacity, but the GE includes a recirculating charcoal filter and an extended service plan, adding value for maintenance. The BLACK+DECKER emphasizes air‑fry and sensor reheat features, which may appeal to health‑conscious cooks. Compare the vent fan CFM (GE’s specifications are unclear) and any extra accessories to decide which aligns with your priorities.

CFM (cubic feet per minute) measures how much air the fan moves; higher ratings, such as 400 CFM on some models, clear smoke and steam faster, keeping the kitchen comfortable. If you frequently bake or roast, a strong vent helps prevent lingering odors and moisture buildup. Aim for at least 300 CFM for typical home use, and consider dual‑speed fans for flexibility.

One‑touch presets simplify cooking but are calibrated for the specific appliance’s power and fan speed. While convenient, they may not replace manual temperature adjustments for precise baking. Use presets as a starting point and fine‑tune time or temperature based on your recipes for best outcomes.

Look for models that include essential features like a durable turntable, LED cooktop lighting, and a reliable vent fan without paying extra for fancy air‑fry or sensor modes. Brands such as BLACK+DECKER often bundle these basics at a lower price point. Avoid paying for duplicate functions you won’t use, like both microwave and convection if you only need convection.

Yes, ensure the cabinet and countertop can support the unit’s weight, which can range from 60 to 70 lb. Verify that the venting system matches your kitchen’s ductwork—some models offer recirculating kits while others require external venting. Proper clearance above the stove and secure mounting hardware are critical for safety and performance.
