I haven't been in communication with the sellers of this product. The person I mentioned, who suggested Oralive is "the next step up" from OPing, is a member at another forum where a number of people have started OPing after my posting about it. She was using Oralive herself and she may have high hopes for it, but I don't think she has any financial interest in it. Anyway, I posted your previous message about the depleting aspect of the clay, and she didn't argue or say anything. Possibly you gave her food for thought.
Again, really appreciate your input on this. From what you say, I don't think the product is worth the cost, even if swishing with clay is a good thing to do on occasion.
