content: Two years ago, I brought it and like it. I drink coffee in the morning, so only used it only once a day. Few month after I brought it, its heat plate started growing rusty. I continuely used it for additional six month when the 50% heat plate was rusted. I thought it was an incidence, so I threw it away and brought the same model again. Nine month late, 20% heat plate is rusted.... This time I don't think it is a incidence again.
