My take on these Colgate products is that they are a great alternative to expensive whitening procedures at your dentist’s office. They’re easy to use, effective and you don’t have to spend a fortune to see visible results. When my samples are finished I’ll definitely be purchasing more of the Optic White line, and since I like to use an electric toothbrush, I’ll probably go for the 360°® Optic White® Powered Toothbrush for even easier and more effective dental care.
