This electric toothbrush is appealing. It is indeed of a long charged with giving it a range of seven days, although most of the users constantly on the leash charging in the base. However, the connection of son does quune fifty centimeters which is not necessarily enough depending on the layout of the bathroom. The handling is easy and enjoyable. This brush has 3 operation modes: cleanliness standard mode, a smooth fashion, a mode soinmassage gums: A light indicates that the brush is too pressed against the teeth, and a timer that it is appropriate to change the quadrant of your mouth every 30 seconds. It comes with 3 different brushes - all Oral B heads are adaptable - and with blue hair discoloring to indicate that the brush must be renewed (however, we regret that the heads are not affected of a number to recognize quickly). A removable base allows you to store the heads, and the brush is compatible with other charging bases. Very good product. However, would not it be smarter to put 20 more and upgrade to version 4000 including a polishing-white fashion?
