Query: Awesome!

Awesome visual effect with an ever changing LCD lighting system and mesmerizing presentation. This product was easy to set up and totally quiet. I am glad the manufacturer said to use distilled water [a small cost] because by using said water this item will last for years. If someone used regular tap water the pump would quickly gum up by all the impurities in the water. A fun toy with some educational properties. I recommend this vortex most highly.
