Have been using them for half a year, unit does not produce hot or cold water so it's always room temp. Old card got stolen and had to cancel it, they delivered water for 3 months before I noticed I wasn't paying, they added an extra 20 bucks a month (roughly 60% of the services cost) and when I called them they replied with "we called you once and sent you a text" last text was in September before my card went missing and they called me at 11 am in the middle of my work shift. Worst customer service Iv dealt with in a while. Canceling now.
