I purchased this distiller and used it as instructed , making about two gallons of water daily for a humidifier. Each night I cleaned it as instructed with inclosef citric acid. After TWO WEEKS the unit stopped working for no reason: would not turn on. I was strung along, told they would send me a board to repair it (???a BRAND NEW ITEM??) and then offered to refund a small fraction of my purchase price and told me to go have it fixed myself. I will be reporting them to the BBB and the US government for fraud. DO NOT BUY FROM THESE PEOPLE.
