Do not use this company - if you have one small thing wrong happen with your account or your aligners it takes weeks to get in touch with someone. They have no email service so you chat with an AI person who can not help. I have wasted so many hours on the phone and that message service with no resolution. I truly never leave reviews but this was ridiculous. I truly wasted 2k and it was so upsetting. They need to have an email service and real humans to talk to to help you.
