Threw away rice cooker since we were family of 4 and mom stopped eating rice and dad wanted to cut carbs. Just not possible to cook 1 cup of rice to what used to be a rice cooker for 8 people. Started to use clay pots since 2007.
Now wife and I was both using clay pots ... 2 drawbacks 1) you have to stand by it for 15 minutes for it to boil so it won't stick 2) you're limited to rice to make based on the pot.
It does make a heck of an awesome Clay Pot Rice (煲仔飯) when you throw in the chinese sausage with crispy crust on the bottom.
