UPS said the account-holder CAN stop transit. Another lie. The next day they emailed to say my order was NOW being shipped and gave me a different tracking number.
Again said they couldn't cancel it and I would have to pay the costs of Return. I had to wait for delivery and refuse it! The dentist reviews warn this appliance could damage gums and tartar and plaque removal are different things.
I now believe their "good reviews" to be bogus. I do not recommend dealing with this company. They do not disclose their actual address either. Highly suspicious!
