I read an article about a woman who used two different products to whiten her teeth instead of spending $600 dollars at the dentist. It was $20 for two trial size products. I ordered them. I did not like the products so I cancelled them online and returned the unused products more than once. I purchased delivery confirmation, return receipt, and certificate of mailing insurance from the post office when i mailed the products back. I was sent notification from the post office when the product was received by CleanWhites who denied receiving the packages...so who is lying, the post office or CleanWhites? My checking account was charged $80+ every month and I never got my money back nor did I ever get a reply from CleanWhites. I called their phone number and got the voice mail of some guy who lives in Las Vegas????? If you don't mind being billed $80+ every month for a product you don't like, purchase CleanWhites but consider yourself warned.
