Thank you for reaching out with your concern. We have tested previous returns and found that they were not rancid. Ozone has a distinct smell that some find refreshing (like rain), while others may describe it as rancid. We are happy to provide a 30-day return window, and if you'd like, we can test the product once we receive it. Please let us know if there's anything else we can help you with
