I did not find this product satisfying at all. I used it for the 1 week to see results but very minimal change was noted. As I have the tooth paste I am still using it until it finishes. Up until now I still havent noted much change, noth even the 1shade lighter promise. It doesnt foam up which took some getting used to at first and I find that my teeth have become very sensitised since using this product.

I see that so many here have had positive responses to this product so I assume the saying "to each their own" applies. But this will be one product I will not be purchasing again.
