I like it.
I've been using it only a couple of times so far and I saw my teeth being whiter. I have been using it after brushing my teeth and my favorite feature is that it has four different levels. Although it's soft, the vibration makes it hard enough to clean the teeth very well, and it's automatic and turns on by itself. The unit came fully charged and It is also rechargeable so that saves me a lot of money and time, this brush is great.
