A few tips for those interested may be allowed to me:
In (almost) all of electric toothbrushes Oral-B series of the same engine with identical rotational and vibrational number infected. So from the point of view it does not matter which model you choose, the mere cleaning performance is the same everywhere. Anyway, the brush attachments fit anywhere (except Pulsonic, but that is anyway clear that this is an ultrasound system). Of course, the equipment and comfort functions and all included accessories are different for each model. You have to know precisely what you need and not what.
Do not be fooled by the model name TriZone. This refers to the supplied brush attachments, but as I said, it all fit anyway everywhere (see above). This must therefore not be buying decision.
The model I purchased does not have Bluetooth, and that's a good thing. Who needs that ?! on earth This is in addition to paid final frills, no one needs to in my eyes. The new mobile app that exist for this purpose, can be had without also use a Bluetooth toothbrush, but even that I think is totally unnecessary.
My experience has shown that it is better to put the toothbrush is not around the clock on the charging station. I invite always completely full and then use the brush until I think that the engine power is too weak. Only then I invite completely full again. That has always extended my battery life. Or with this method reaches the battery endurance still very long, even after years. If ever in-the charger brush on the other hand, the battery lasted for some time, only 2 or 3 days. And that deteriorated rapidly.
All in all: strong buy recommendation, price / performance ratio good!
