The battery lasts at my toothbrush - as described in the product description - between 4 to 6 days. This time is enough for me from absolutely, because I Normally the toothbrush anyway have every 2-3 days on stream.
How did the toothbrush from other electrical brush unterschreidet, of course I can not judge. But compared with my manual toothbrush I can say that there is a huge difference. The teeth feel much cleaner. Especially the necks of teeth and spaces are cleaned much more effectively.
So if you like I would for the first time to try an electric toothbrush can not get to on this product!
