This watcher pitcher works great! I got it because if acid reflux and this has been tremendously helpful! The pH of my pitcher is usually closer to 8 than 9 However, I think my water is really acidic and I can feel the difference. Also, this is some of the best tasting water I have tried. Even my family agrees. Lastly, I notice that I don’t drink as much water when I drink alkaline water because it’s more hydrating! If your considering purchasing I’d say it’s definitely worth the investment!
