Is it normal for smells to return?

there are no instructions on how to use this? How do you clean vegetables with it? Whats the correct dilution to make "ozonated water"?

Voltage? What is the watts draw? Is the ozone generated by ceramic plates or a spark?

What are the little balls that come in the bag for and how are they used ?
