I have been using my Zenyum invisible aligners now for a month and am also waiting for my Zenyum white order to arrive. The journey with Zenyum has been really good so far. Their customer service is very responsive. Kelly and Jessica are very patient and efficient to answer my questions. The whole Zenyum treatment is also very affordable when compared to traditional braces and the market leader Invisilign. Their pricing structure is also transparent. Best of all, they guarantee results or else they will produce more aligners to correct your teeth for free. It may be uncomfortable to wear the aligners for the first few days. But it quickly gets better as my teeth start to shift. Compared to traditional braces which I have heard gives you ulcers and are hard to clean, this is much better. Also, it's invisible to no one knows you are wearing braces. An additional benefit is that because you aren't supposed to eat or drink anything except plain water while wearing the braces, it helps to cut down in on snacking which is like a free weight loss program. Hahaha.
