Love the affordable price of Zenyum! Staffs are friendly and so is the dentist. However, since there were some steps involved (e.g. pre-purchase, finance, post-purchase), I have to contact different staffs at different steps. Generally very satisfied with the service but was caught off guard when I was told to continue my last set of aligners until the retainers are ready in about a month time, didn’t expect the production time to be this long.
