I bought this because my dentist recommended that I use an electric toothbrush. I had used some less expensive ones in the past (a different brand), and didn't mind them, but went back to manual toothbrushes eventually. This time, I decided to get a Sonicare, even though it was more expensive, as it seemed like it had good reviews. When I got it, I was excited to try it, and the packaging and accessories all looked nice. But the feel of it was awful--I stopped brushing after a short while and went to read the manual more, thinking maybe I was doing something wrong. I realized there was an an "easy start" feature, which I turned on and which made it a little more bearable, but not by a lot. And after reading through the manual more, I realized that certain features for which I had bought the toothbrush (such as pressure sensor) needed to be activated first (I thought that would be automatically turned on). I had to navigate through the manual and listen and watch for a certain series of beeps and lights to try to figure out if I had turned it on or not. There are different beeps, tones, and lights which try to tell you which features are turned on and off, but I found them fairly confusing, and I went through about twenty cycles trying to make sure I had turned on the pressure sensor. Also, it doesn't seem like the toothbrush stays on long enough to brush all your teeth properly. Maybe I'll get more used to it (if I can stand it long enough to get used to it), but it just seemed like it didn't stay on long enough. I tried a couple of times with this toothbrush, and after the second time it turned off, I finally just decided to brush my teeth with my manual toothbrush. Also, after all that I went and re-read the manual yet again, and I noticed it was a manual for the 6100 toothbrush (and not this 4300 toothbrush). I'm sure that contributed to my confusion about the settings. Also, the pictures for this item show a tongue brush, but that was not included in my package. Furthermore, the package says there are two intensity settings for this toothbrush, but the manual does not say how to switch between them or tell which one is activated (actually, the manual says there are three intensity settings and that I can press the mode/intensity button to change them, but that button only exists on the 6100 model, and not this 4300 model which I have, so I have no idea how to change the intensity).
Lastly, the brush head that comes with this is so small that it takes a really long time to brush all your teeth. Every time I brush my teeth, I have to turn it back on several times, as it turns off before I have brushed all my teeth.
