M 20 Cube Ceramic
Design microwave with ceramic floor
One turn ahead - The CASO M 20 Cube Ceramic with innovative CUBE controller
Instead of complicated buttons or difficult-to-understand dials, the innovative Cube Controller enables intuitive control with just one hand. Programs, power levels and cooking times can be easily set by turning, pressing and tapping. This unique cube operation not only makes everyday life in the kitchen more convenient, but also more precise - for perfectly cooked food at the touch of a button.
Modern design and powerful technology
With its high-quality stainless steel finish and stylish LED lighting, the CASO M 20 Cube Ceramic makes a real design statement in any kitchen. However, it is not only visually impressive, but also technically. The 800-watt microwave mode offers ten individually adjustable power levels so that every meal can be prepared perfectly. Whether quick heating, gentle defrosting or even cooking - this microwave adapts perfectly to your needs.
More space, more possibilities - without a turntable
A real advantage of the CASO M 20 Cube Ceramic is the flat borosilicate glass base. Without a classic turntable, the entire 20-liter interior remains usable - ideal for large plates, rectangular casserole dishes or several dishes at the same time. The innovative microwave technology with integrated reflector ensures even heating and perfect cooking results. This gives you maximum flexibility and even more efficient use of your microwave.
