Their website claims you can get a free trial of the product for only the cost of shipping and handling. What they don't tell you is the trial period is 14 days. The product takes months to whiten your teeth if it works at all. At the end of the month you get billed $79.95! If you don't cancel your order in the 14 days from the time you receive the product, they will keep sending you this small tube for the ripoff price. Also you have to return the product to then in that time frame with the cost of insuring and tracking plus postage in order to not get billed. Stick with over the counter whitening strips, they work!!! read full review »
