This site is a scam. Also Known as DENTA SMILES, It is in Kahoots with Vibrant White, they are a team, they say they work great together, yes they do; to rip you off! They offer a free or low cost trial. But before you can even use it, the are charging your credit card $79. then the phone num the list, to cancel does not ring, the email address the list when you go to send does not go through. And if you liked this product, wouldn't you order more when you ran out any way? But no they don't give you that option, they just force it on you; kinda like finacially raping you; because you get it whether you want it or not and you have to pay for it to and there is nothing you can do about it. Great offer huh? Try it, go to cancel page, see what you get; rerouted to nowhere...
