Battery lasts longer despite my brushings few days - absolutely OK. And put on the glass it is anyway, and every few days there will be newly infected. Let it not be permanently connected to the network because I unnecessary standby currents - and they are still so small - avoid.
What, unlike a few years ago tried Oral-B I find very beneficial is that the brush heads have no opening, reinzieht through which air. I like to brush with "closed system" where no air can get in and nothing else. You understand what I mean.
