After a month of use I can say that the brush is excellent. Although it comes charged, I preferred to plug it in before the first use, it takes about twelve hours to fully charge and after two weeks it reached the last point and I charged it again.It has five brushing modes, but the first one is enough to achieve a good cleaning. You can download a phone app to which it connects by bluetooth but I haven't tried it.At the same time, it comes with a base to which the charger is added, a spare brush and a travel box that is very good.The strange thing is that although the box was closed and in perfect condition, the plastic of the brush handle is as if worn, but it does not affect the operation.I recommend it
