I use this unit for water distillation. Afterwards i put it trough a separate carbon filter and then it tastes good. I like that all the surfaces tuching the water are stainless steel, and the holding container is glass. It' s ok with me that the digital temperature gauge is in celsius only, but if you have to know the temperature in fahrenheit then you have to do the math yourself, but this only goes for if you use this unit for other then water distillation. Otherwise for water just put it on the highest setting. You can also make flavored water using herbs or flower petals etc.
