Everything is fine! The water is good, crystal clear and there is no scale completely. One drawback is that you need to have a penny, the machine does not give you change. This problem is solved by installing the "pay" program. We use it all the time, since there are two vending machines nearby.
We constantly take water in this apparet, I'll tell you a secret, we did our tests with different strips and devices, this water is really better than the purchased one!
