I have been using the Colgate 360 toothbrush for about 6 or so years now. When it was time to buy myself a new one, I went to the pharmacy to buy one but saw the Colgate 360 Optic White Toothbrush was on sale. The name made it seem like it was something special. It made it seem like it would work even better than the regular Colgate 360, and the fact that it was on sale, I just knew that I had to buy it and try it. The next morning when I went to brush my teeth, I took the toothbrush out of its package and looked at it carefully. I did not see a difference in the way it looks. It looked just like the regular Colgate 360 toothbrush, and after using it for a week, I noticed that it did not perform half as good as it. I was so disappointed in the performance of the Colgate 360 Optic White Toothbrush. I felt as if it was barely cleaning my teeth, and I found myself brushing them harder than usual. This made me hurt my gums and caused them to bleed. The next time I need to buy a new toothbrush, I will not be buying this one. I will stick to my favorite which is the regular Colgate 360.
