I'm sure that these reviews are legit and the company is great during the process. However if you plan to cancel before your aligners they will dodge your calls, ignore your emails for weeks. It took me two weeks to get a hold of someone, and he did everything in his power to keep me even though it would not have worked out for me. I was waiting for another set of impressions, and so because of wanting to cancel instead of sending them in and canceling afterwards which would have taken at least a month, they're keeping $80 for the impression kit. For one, that's $80 for some putty, and if I would have done the second round of impressions and waited I doubt I'd get a hold of them right away. However I just said I would take the loss because it was so much effort to reach someone, and he sounded almost angry at me and pretty much hung up right away after that. I was considering when I moved back to this country to try this again but I will definitely be choosing another company now. Stay away unless you are certain your life circumstances aren't changing/you are 100% serious about buying because otherwise they'll take your money and ignore you unfortunately.
