Turntable
The presence in the design of the microwave of a turntable (glass disk), on which a dish is installed for heating or cooking. The rotation allows you to heat food evenly. At the same time, there are solutions without a turn table at all — a smooth flat bottom is easier to clean. In this case, no additional energy is spent on rotation, which favourably affects the noise level.
Turntable diameter
The larger the diameter of the table, the larger dishes can be used in the oven. This spec directly depends on the volume of the microwave oven.
Country of origin
The country in which, according to the manufacturer, the model is manufactured. Even though most of the capacities are located in China, European factories for the production of household appliances have not disappeared. And some models can be produced on them. In general, such a division into a Chinese or European factory should not particularly affect the quality of products but the stereotype of a reliable European assembly is present. However, it is possible that the model may have a country of manufacture, for example, Poland, and in the store, under the same article, you will meet China.
