Got this yesterday. i set it up, and a few hours later I had a gallon of distilled water. Put some in my CPAP humidifier - and no residue in the tank this morning. Great. But - the instruction sheet was a typical poorly translated document, and two parts in a separate bag were not mentioned. So, I tried customer support - the chat was useless. An email seemed more likely to help. Wrong. I enclosed photos of the distiller, the parts not described, and some simple clear text. What is this a picture of. The email got a response. We went through a few emails and responses, with the support persons different with each exchange, asking the same questions over and over.Bottom line - nicee distiller , lousy support.
