As our large rice cooker always problems with smaller portions makes, we decided also to buy one with only 0.5 / 0.6 liters. One criterion was the warming function, which does not have any models.
The Sencor (0.6 l) has not met expectations and cooked each 1 -2 small bowl of rice without any problems. However be after 2-repeated use currently no "long-term experience".
It would also be useful for traveling with a drive through the small mass.
