Initially I was a bit recalcitrant to the idea of using an electric toothbrush although my dentist me has repeatedly recommended and my companion who has yet. The base load for 16 hours (as indicated), but this model no charge indicator contrast to the more high-end models. The base does not take too much space in the bathroom or traveling, she is sober. Taking hands is easy. The timer function is very convenient and allows you to brush your teeth during the ideal time, but on the more high-end models every 30 seconds indicates a signal to change the area to paint. The two heads can change the brush "clean precision" standard in oral B is the one I used because the brush "3D white" is harder. As for ease of use, you feel a real plus compared to manual brushing that remains superficial, and the same feeling as when leaving a dentist after descaling. I think it is a good product, ideal for beginners, but that makes you want to have more high-end models that have many practical functions such as battery indicator, the charging indicator, the excessive pressure detector and brushing the teeth in 3D. The downside is the noise of the toothbrush which is quite noisy, but you get used to over time.
