I have signed up for Zenyum and currently under treatment plan for a bit over 1 month now. Therefore, results are not yet visible, but I'm impressed by their excellent customer service and dedicated staff. The app is very neat and easy to use and is a good way to communicate with the Zenyum team as well as the dentist who's treating you. The prices are really good compared to the alternative (Invisalign). I hope my results will turn out satisfactory, and so far the journey has been smooth sailing and the braces are very easy and comfortable to wear.
