Mon conjoint aime utiliser cette brosse à dents à batteries. Il trouve que cela nettoie bien et laisse la bouche propre et fraîche. Pour ma part, je préfère utiliser la brosse à dent manuelle car je peux mieux contrôler la force d'application et la direction. À chacun ses goûts.

I've been using this toothbrush for years, and I've been pretty happy with the results. I mean, though this product boasts that it "whitens" teeth, I don't really believe that. But if they use it as a marketing tool, then it should have some grain of truth to it, right?

It's very consistent with enough voltage in the battery, and it makes brushing my teeth easier. Of course, who brushes their teeth with a manual toothbrush now that we have so many electronic options available to us?

The brush needs to be replaced every 3-6 months, and 2 of them costs the same amount as a new toothbrush. The buttons are made of plastic/rubber, so after all these years, they've started to grow old and fall off. Also, now, I think that there's something wrong with the place where the battery is attached, because the toothbrush cannot be powered, even with full 1.5V batteries. They're good for 5 or so years, I guess.
