I was excited to get my new Hydrogen Stick. I wanted to possibly sell this product in my webstore. But then I tested it. See this test here in the “Don’t Buy the Hydrogen Stick” videos. Since the water is not forced through the stick (as it would be with a filter) it doesn't get changed very much or very quickly.
The reason I say " Don't buy the Hydrogen Stick," is that it would be a waste of money. See the videos.
