Very good value for money. I had already an electric toothbrush Oral-B much more expensive ... and I honestly do not see the difference! Very good battery life (starts to wane after about ten days without load) I like the principle of the signal every 30 seconds, which encourages good brushing teeth 2 minutes. 1 single program, but why do more? I find it hard to grasp the interest of creating 50 different models of electric tooth brushes ... This is a very good investment.
