I was using this at my store until last month. It still works without any problems. I, who have used it for three years, think that it tastes delicious if you cook it with a little less water than the standard amount. The year of manufacture is unknown. The reason I'm selling it is because I bought a 3-sho rice cooker and no longer need this one. There's almost no rice sticking to the inner pot. There are some stains and scratches, but I think the operation is really good. Feel free to negotiate the price.
