Used them for many years until this past month they denied 4 of my impressions without notifying me, poor customer service, no good explanation of why was denied. A complete waste of 2 months, because they do not communicate neither care you are waiting for your night guard. Find someone else!
Tip for consumers: They are a waste of time, they wont get your guard approved. I have years experience making them and after 4 they never approved them, I think they do not care. They kept shipping cost and the cost of an extra shipping kit. A waste of time and money.
