I received the Colgate Optic White toothbrush with whitening pen and toothpaste complimentary from Influenster. Being a coffee drinker my teeth do tend to turn alittle yellow. After a few days of using the products, I am surprise to see the results of my teeth turning white. This product is excellent and I recommend it to anyone who needs a teeth lightening. The taste is great and the price on the products is fairly decent.
