COSMO’s 30-inch freestanding range packs a serious amount of cooking power into a standard-sized footprint. The COS-305AERC is built for the home cook who needs flexibility, offering a five-burner ceramic cooktop with two selectable-size elements. This means you can switch a large burner down to a smaller one, saving energy when you don’t need a full blast of heat. It’s a practical feature that adapts to your pan, not the other way around.

The real workhorse is the triple-element burner. Its 4700W total output boils water quickly, while the ability to drop down to 1600W or 800W gives you precise simmer control. The oven’s 5-cubic-foot capacity and convection system are designed for even baking and efficient roasting. You’ll notice consistent browning and shorter cook times. The dedicated 100W warming center is a small but thoughtful touch for keeping sides or sauces ready.

Installation is straightforward since it’s a standard freestanding unit. The smooth glass cooktop wipes clean easily, though it shows fingerprints and spills quickly. This is a capable, feature-focused range that prioritizes cooking performance over aesthetic frills.
