This rice cooker replaces another, bought at 25 in a Chinese store but damn few months. It really is perfect for cooking various rice. The tank cleaning is done with a damp cloth; everything comes off very easily (nothing sticks, actually). We are delighted with our purchase and our rice never had the desired consistency as easily!
I recommend the eyes closed.
PS: for the couscous by cons, it is not effective at all: -D
