According to the video if you order the whitening kit your first package you will receive an extra mold set to take a mold for the whitening tray and Whitening Gel, however I did not receive either item. I contacted customer service and they told me that it would be in the shipment of retainers, it was not. I actually don't even think that I received the official retainer what I got was an extremely flimsy non -tooth conforming tray with my name written across the front teeth. F this isnt just a whitening tray, Why would you write visible writing across the front teeth on something that supposed to be invisible aligners? They don't click to the teeth or stay in place at all. I verified the my entire tooth impression was in the mold with gumline. I sent a complaint with photos a week ago and have not heard anything back. 100% dysatified in quality and communication!
