I wish I would’ve found this a long time ago. I’ve had a water delivery service for 10 years and it is very expensive. This is the most high-tech, convenient and top quality system I’ve found and couldn’t be happier with its performance. The machine pays for itself in three months based on what I was paying to have water delivered. Not to mention that you can add a mineral filter. I’m very happy with my machine and especially like the UV feature.
