I ordered this product because it is battery powered and therefore wireless, which is more convenient for you travel and do not require a decision in a tablet. The only drawback: the plastic cover of the toothbrush. He ends up damaging and Rachette when a brush is not provided new protection of the brush. Too bad! Closing the battery case is not so great and can break easily. Despite all this, I will continue to buy this product because this brush is very cumbersome because it can not be powered on a stand abreast.
