I have had this for about a week now, have made one batch of sushi short grain rice that rivaled any I have had in sushi houses, have had fresh, hot rice jook (rice porridge) two mornings this week, oatmeal one morning (check the Zojirushi website for cooking compatiblity on machines that don't have the specific functions) and fresh, hot white or brown rice ready for me when I got home, one time at 17:00 and twice after 21:00, so I can definitely say that the keep warm function works.

Selling points are its compact size and many functions.

Easy to use and multiple functions.

Good function and easy to clean

The keep warm function makes it taste like it was cooked fresh up to two days later

Another awesome note is that it has an exceptionally awesome 'keep warm' function that far exceeds other rice cookers I've used

Excellent rice cooker!Timer function is awesome, just set it and "voilà": fresh rice at schedule time!Ps.: just follow exactly measures.

The timer function works

The 12 hour warm function is fine for a smaller model such as this one

and I love all the functions
