Anyone ever tried these? I bought them the other day (for $40!!!) and am hoping they work. My teeth are actually a good strong white, but I'm always hoping for even better!
They have a money back guarantee after 14 days. But that means nothing since no one ever does that and I think I already lost the receipt.
So anyway, positive experiences...negative experiences....?
