No customer support and bait and switch
There is absolutely no customer support or assistance as you are going through the aligner process. There is even less support once you are in retainers. DON’T BUY THEIR PROTECTION PLAN. Get your retainers somewhere else. They promised that they would send impression kits before each set of new retainers but after I paid for the service they now want me to go to my dentist AND PAY MY DENTIST MYSELF for a 3D scans to make new retainers!
