The family size Panasonic NN-ST452W microwave, finished in white, features 6 power levels for versatility while cooking. A large 27 litre capacity makes this oven perfect for family use, and boasts built-in inverter technology that provides more even and constant cooking. This technology also reduces the weight of ovens, making for easier cleaning. Chaos defrost gets food thawed more quickly, and with a child lock you can enjoy complete peace of mind when using. Please note: for proper operation, the oven must have sufficient air flow i.e. 5cm at one side, the other being open; 15cm clear over the top; 10cm at the rear.
