I use this toothbrush for a little over 2 weeks and I love it. I was a fan of manual brushing but I measure the difference since I started using this electric toothbrush: teeth are immaculate, the gums are protected, brushing time is respected through the box that is connected to ... It is a very playful toothbrush and very easy to use. I was afraid not to understand the operation, but after the first charge, it is turned on and the connection to the case is done automatically! Finally, the different brushes to adapt the brushing her needs: white teeth, sensitive gums brushing ... several programs are available very easily on the case. It's an investment but I recommend!
