For German speaking this cooker is ideal because it provides brownish, crisp rice.
For Africans this stove is partially suitable, because the burnt rice at the bottom is too little in order boil rice water.
For Asians this stove is entirely unsuitable because so no white rice can be cooked. The cooked rice is not for sale to Asians, it can be output to a maximum of German speaking guests.
We use the machine now only to keep warm. Our rice is cooked in our imported rice cooker from Thailand.
