I got the starter pack, followed the instructions, stuck with it, and I got results. The fact that I got results - 4 stars. For the results that I got - 5 stars. My teeth are noticeably whiter.
I've tried whitening strips before (crest whitening strips, whitening trays, whitening toothpaste, etc.), but I believe the key was the combination of the sonic toothbrush with the whitening strips.
I did not use the Ollie toothpaste, though. I used a store-bought whitening toothpaste without fluoride. I still got noticeable results. However, with the results that I experienced without the Ollie toothpast, now I'm curious how much whiter my teeth would be if I had used the Ollie toothpaste. - Shoulda, Coulda, Woulda.
