This is very, very simple machine, but it is what I wanted. No digital display, no option to set temperature, just hard press buttons for on/off as I planned to distill water from my well only to make it drinkable. Also, it does turn off by itself in case you forget you are distilling water. You will get about 3.5 liters of distilled water in one go. I would recommend this machine as a means to water purification for health conscious people, whether you use it in your hot drink, to dilute juices or to drink it on its own.
