I got started on testing right away. I was happy that they included a test tube of Colgate Optic White toothpaste. It was the perfect compliment. The toothpaste had a minty taste without being overpowering. So I brush, brush, brushed, then I popped the whitening pen out of the end of the brush. Two clicks for the top teeth and two clicks for the bottom was more than enough whitening paste to cover my teeth. At first I was a little worried that the paste was going to be visible on my teeth throughout the day, but it after a couple minutes it wasn't noticeable.
So far I've used the new brush and pen for 3 days and I have noticed that my teeth are getting whiter. It's an easy to use system and I love how the pen fits in the brush. My tips for the whitening pen is that you dry your teeth off before you use it. It makes it easier for the gel/paste to adhere to your teeth. I can't think of any recommendations for this brush, but for a future brush I would love to see one that has an insert that slides in like the whitening pen except that it is full of toothpaste, and you could click the handle and toothpaste would come out of the brush! I think that would be really cool and handy.
