The result is great-tasting, naturally mineralized water with the same chemical properties as the finest alpine springs — now available, on your countertop.

We really like this but the instructions could be clearer. I had to use Google Gemini to figure out how to get the cold water to work. There is a switch on the back. The other thing is the water has to be refilled regularly. We refill it at least once a week with how much we use this. Otherwise we like it and its pretty. We havent taken off the instructions yet since it took a bit to figure it out.. Givona. Temecula, CA. Sat Sep 19 2026
