Jai long thought that the electric toothbrush wasnt quun gadget made for lazy and I realize that I am wrong. Jai was totally conquered by this electric toothbrush Doral-B. Firstly it is very light (no more heavy manual tooth brush quune Vive progress!), It is well in hand and really feel what makes it easier to brush his teeth. In addition, it has a long battery life (about 10 days lutilisant 2 times a day), plus waterproof. In the end, it really is a product that I recommend.
