I drink a lot of tea, so I love having hot water on demand. We haven't had any problems with this yet, but we've only had it for a couple months. I see no reason why it shouldn't last for a long time, but only time will tell. It is easy to use and does everything it says it does. I like to boil water at night, maybe have some herbal tea, and rest assured that I will have hot water in the morning when every minute counts.
