I purchased distiller to provide drinking water for 3 adults, 1 dog, & 1 cat. I personally drink 1 gal a day. I have been using this distiller every day for a month now. I make 1-3 gallons a day. The price was amazing compared to others I viewed. I expected the insides to require some scrubbing to clean. Makes a gallon of distilled water in about 3hrs using hot water! I am happy with this purchase. No problems, worth the buy.
