Cosori
Hot air fryer with viewing window

The COSORI hot air fryer with viewing window is a versatile kitchen appliance that has been specially developed for healthy and efficient cooking. With this hot air fryer, you can deep-fry, roast, bake and much more – all with minimal use of oil. The large 6.2 litre capacity provides enough space for larger meals, making it ideal for families. A particular highlight is the large viewing window with interior lighting, which allows you to watch the cooking process without opening the deep fryer. The eight preset programmes and quiet Whisper-Quiet technology ensure convenient and quiet operation. We were impressed by the ease of cleaning thanks to the non-stick coated surfaces and the good workmanship. However, the initial plastic odour, which appeared on some appliances and only disappeared after several runs , was a negative. Overall, the COSORI hot air fryer offers an impressive combination of functionality and convenience, although there is still room for improvement.
