This is a typical tech company who went to market without having fundamental customer service and fulfillment in place. I went through the initial consultation and received my aligners with a few issues, and my teeth started to align, but when I needed a replacement set of aligners, it took months, and my teeth reverted back. Customer service repeatedly lied and said they were overnighting them or they would be there in a week (etc., etc.), but it took months. I had to go back in trays to fix, which was a painful process.
I finally finished and now it's been months since they were supposed to send my retainers and my teeth are reverting back again. I won't go through the process again and am trying to get my money back.
Bottom Line: No, I would not recommend this to a friend
