So I bought this toothbrush as it was reviewed the top toothbrush. After just been to the dentist and having a good clean up I was eager to start my journey with my new brush. When I first used it, I found it very 4 it tickled certain areas. The vibration is very powerful and left me feeling like I had a very clean mouth. I will warn you that it is very powerful and if your not used to using an electric toothbrush you may want to be careful and gentle to start with. I was a little over enthusiastic when I first started and managed to give myself ulcers. This I feel was user error though not the toothbrushes fault. I like the 3 settings and recommend using sensitive until you get used to it. The button is sensitive which I like, you just have to mind you don't turn it off. It beeps after 30 seconds so you know you need to move to the next section. It came fully charged and so far, i have not charged it up, and it's been 2 weeks brushing twice a day. I would recommend it. I have only not given it 5 stars as I want to see what my dentist says about my teeth and if it is working as well as I think it is.
