Did not whiten my teeth... but then it did

Product is easy to use and doesn't cause irritation but it did not whiten my teeth after 1 and a half weeks of usage. I actually notice no difference in my teeth. After using, my teeth feel cleaner but they are not brighter or whiter. I was misled by the raving reviews that show pictures of dramatic before and afters. Again, this product did not make a difference in whitening my teeth while used as directed. I would not recommend it as a teeth whitening product nor purchase this product again. UPDATE: It DOES whiten teeth! It just takes longer than the suggested 2 weeks some folks are saying in their reviews. I've been using it for over 2 weeks and slowly but surely my teeth have become whiter.
