With this halogen oven, you can prepare a delicious, vitamin- and nutrient-rich meal in less time than with traditional methods. The halogen oven bowl is made of glass, so you can clearly observe the cooking process. It has a large capacity of 7 L + 3 L (with the included extension ring) to accommodate large quantities of food. The oven cooks food by circulating the hot air around the food evenly and thoroughly, and thus requires less cooking time than the average convection oven, which makes it energy and time saving. The extension ring helps you enlarge the halogen oven's space for larger meals. Accessories include a low rack, high rack, tongs, an extension ring and a lid holder. Assembly is easy.
