At first, I was a bit skeptical about the product, but after the first try application, I totally see the results instantly. It's really better than I expected it to be.
I bought the Teeth Whitening Kit and Day & Night toothpaste. The Teeth Whitening Kit has to be applied every night before bed for six nights. At the last application, it got my teeth two shades whiter. For better results, use the Day & Night toothpaste.
Don't hesitate to get the product; you won't regret it.
Bottom Line: Yes, I would recommend this to a friend
