Summary: This is the second unit my wife has had, the other one just died after four years of continued and constant use. She is Korean and drinks a lot of tea and mocha so it is used at least fifteen hours a day.
Summary: So far so good. This is the pump one where you have to manually push down. It costs about $25 more for the special, electronic button. I'm not worried about rust any time soon, except that the water provided through the sink leaves traces of calcium inside of the water heater. Yes, a trail of white, crystal like salty grains are left behind if you leave the water inside (2-3 days).
Summary: This unit is great, the water is hot when you need it. I am a one cup coffee/tea person and this works great for me. I did not take the electric pump model for it is just something else to go wrong with the unit. The reason for the 4 stars is the pump unit on top is not as good as my old unit.
Summary: This is the second one of these pots that I have owned. The previous one lasted about 15 years. In this day and age, a small appliance, continually heating water 24/7, lasting 15 years is almost unheard of.
Summary: Outstanding product, been using Zojirushi products since my days of being stationed in Japan in early 60's.......would purchase another product, currently use two different rice cookers made by this company......
