The ads for this product looked awesome and made me really want to see what all the fuss is about. The taste of the toothpaste was fine and the price is reasonable for a Whitening Toothpaste. Unfortunately, I used it for three weeks without seeing much if any of a difference. I have stopped using it and are now testing other brands. I have sensitive teeth and is currently getting more results with Colgate Sensitive Pro-Relief Whitening.
