Review (4/5): Seems to work quickly..
I just bought this product, have brushed my teeth with it once and they already looked whiter! I'm very curious how they will turn out after a week of using. The toothpaste had a nice consistency and tasted pretty good, too. I would say it's a good buy! I gave 4/5 stars because I'm not sure yet if it's going to affect enamel or not. I'll be writing another review after I see.
