Product Summary

The size 5.5 cups is prefect for a family of 4 and 10 cups is perfect for a family of 6 +.

The delay timer function is great for a busy household (you can set the timer in the morning and it will be ready by the time you get home!).

The heat source is at the bottom of the rice cooker for the micom (microcomputer) rice cookers, however, this model has the triple heater (bottom, side, and lid) to generate heat all around for even heating.

It is a great rice cooker for you if you are looking for simple and affordable model with an ability to make quality rice.

What is Fuzzy Logic technology?

This model comes with the micro computerized Fuzzy Logic technology. The fuzzy logic controller microchip in the rice cooker can think like humans and adjust the cooking temperature and time to make the perfect tasting rice every single time! (more details are explained in this article about the fuzzy logic.)

 Inner pot peeling after two years
– It doesn’t keep the rice good for long

Source: www.amazon.com

It is recommended to use the bowl or strainer to wash rice to preserve the inner pot. Read this article for more tips on how to preserve the inner pot for a longer time!

It is not recommended to keep rice warm for more than 12-24 hours in a rice cooker. It is recommended to freeze cooked leftover rice to keep the freshness.

Make sure to wash/rinse rice before cooking to avoid the odor after cooking as the rice bran can be the cause for the odor.

In addition, improperly stored uncooked rice can be the cause for the odor after cooking. it is very important to store uncooked rice in proper temperature and place. It is recommended to store them in temperature below 15 °C with 70% humidity in a place not exposed to direct sunlight.
