I was looking for something that would improve the quality of my water. I can see a difference in the water - it has lots of tiny bubbles and tastes different. I simply place my glass or jug on it - a very simple way to be a bit healthier. The only issue was that it came scratched, but Auravita kindly sorted this out. BUT you do have to be careful not to get water on them as it can get inside and effect the magnets (this happened on my last one).
