I find this rice cooker to be very convenient.  I read the reviews before I bought it and saw that one of the largest complaints was that it boils over.  It has done that to me and I've found that it won't boil over when I add a little olive oil and use the silver steamer basket on top.  Before, I had this rice cooker, I cooked rice on a gas stove and had to worry about it boiling over on that...even in a large pot and cleaning up the rice cooker is much less labor intensive than cleaning up my stove top!  That being said, the rice comes out perfect...I follow the directions in the booklet that came with the cooker...and the cooker has a warming mode once it has finished cooking.  Would be nice if it automatically shut off after a while.  Overall, I'm very happy with this purchase and would buy it again.
