You can still get the containers, but you will also need the Energizer audio, and a headset. Your water will be energized in about an hour per gallon. The louder you pay the audio, the more energy it transfers to the water.
The Energizer® audio is like a comb... it removes the incoherence from the water that makes it impossible for the body to use it. It creates coherent sweet silky water that nurtures your body and your soul.
Here is link to the article that describes the Energizer® audio... how it works, etc.
The main reason you want wide mouth bottles, because no matter what you do, moss will start to grow in your bottle. It is easy to remove using store bought hydrogen peroxide and a brush. Clean your bottle at least twice a year.
