This electric toothbrush is beautiful to look at and my daughter was thrilled at first and would prefer to clean not only your teeth with it. The design is beautiful and suitable for children (girls). The small brush is ideal for the child's mouth. The volume is okay, the vibration just fine. Likewise, just fine, is the thickness of the handle. For small and narrow finger he could be narrower. Overall a nice part, self-explanatory and instinctive to use. Battery change as easily. From our strong buy recommendation.
