I bought the "buy one/get one" for $26+. Then the next month I was charged for another shipment. When I saw the withdrawal, I called and they said it was too late to cancel this shipment. I canceled the "membership" and they charged me for the next shipment even though I didn't receive it. They wouldn't let me speak to a manager. I reported to the BBB, and so far it hasn't mattered. The product didn't work for me and made my teeth really sensitive. So, I didn't even use a tube. I ended up paying $116.70, which I didn't authorize in the first place.
Pros and Cons:
Bottom Line: No, I would not recommend this to a friend
