Well, it worked.
My teeth are definitely whiter. It doesn’t taste GOOD, but it’s not terrible or even grimace-worthy. My biggest complaint is the clumping brush and how difficult it is to get the sticky left over product off of it before the next use. Even if you wash it immediately after using, its as difficult as cleaning old product. It just cakes and sticks to the brushes. If that could be solved, I’d immediately give 5 stars instead of 4.
