After our children is sometimes a bit struggled with the correct brush, we decided to buy electric toothbrushes. With simple models (eg oral), we have not had good experiences with regard to the battery life. In this respect, the reviews for this model have been encouraging and the offer with 2 hand parts, 2 cases (1xHartschale) etc. attractive. After now 3 weeks, the children brush better, the coverings have declined markedly in all of us. The battery life when using 2 hand parts with 4 persons 2x a day is pretty much 1 week. This is i also for a holiday. O. and I hope we can still increase slightly the. The hand parts themselves are intuitive to use, quiet and effective. Clear recommendation extent.
