I really wanted to like this toothbrush. I was told by my dentist that I have to take better care of my teeth and he recommended trying an electric toothbrush. I purchased this and a Sonicare model and have been trying each over the course of several weeks at a time. In my estimation of eating things like spinach which I can gauge how well it cleans. I would say that the Oral-B is better than the manual brushing but not as good as the Sonicare. What I really like about the Oral-B is that I can feel the brush cleaning my teeth and feel like I'm brushing. With the Sonicare, you are not supposed to actually brush but simply to pass and hold the brush over your teeth at gums at the 45 degree angle and allow the brush to work (also it takes some time to get used to how noisy the sound is in your head). If you are coming from a manual toothbrush you will be happy with this. But if you really want clean teeth I would recommend getting a Sonicare.
