Review (5/5): just buy it
After reading all the reviews and because of my hatred for the way regular whitening products make my teeth feel, I had to try it and I was not disappointed. This is the pictures I took, in the same exact natural lighting with no flash just a few minutes apart after using it for the first time. I dont feel bad for being a daily coffee drinker anymore cause I can maintain the surface stains without having to give up cold beverages and food for uncomfortable whitening treatments.
