The black Upo OPS737B built-in oven has an A+ energy class and an easy-to-read LED display. The oven is user-friendly, and its arch-shaped design, along with efficient air circulation, allows you to cook on multiple levels with ease. You can bake cookies on up to four trays at the same time. Thanks to excellent thermal insulation, the outer surfaces of the oven are always safe to touch, whether it's a child's hand or a dog's nose. The oven has a large capacity of 77 liters and is rated A+. The pop-up knobs are ergonomic to use, and since they can be pressed down into the panel when not in use, cleaning is also easy on the flat surface. If necessary, the glass on the oven door can be removed for cleaning. Included with the oven are a specially deep tray, two lower baking trays, and a rack. A child lock comes standard, and it can be turned off if necessary. You can also adjust the brightness of the display. The cooking functions of the oven can be used automatically; you can select the desired cooking time or desired cooking duration and end time, which is particularly handy for timing breakfast porridge. Of course, you can also use the oven normally without timers by simply selecting the temperature, oven function, and turning it on. The oven also features a unique air frying function, allowing you to prepare small ready-to-bake portions in a healthy way.
