For entire brush:
Almost as light as a normal manual toothbrush and accordingly I had to get used not by the handling.
At first I was a little irritated because basically vibrates the brush head "only". What should have to do with that sound is not clear to me.
Since the vibrations rather meet a phone I was very skeptical whether the ever brings what.
Yes it does, insofar as they are not too tight impresses this brush cleans really better than a manual toothbrush.
In principle, as a sander: D
The battery lasts about one week at 2-3 times a day cleaning.
Very sad is that there is no indication when the battery is coming to an end. The brush is made easy. Very annoying when you have just begun with the brushing.
For charger or brush holder.
As I put the brush to use always the same in the station I can say nothing about the charging time.
But really annoying is the far too low weight of the charger.
This is so easy that it is raised including toothbrush through the cable. The cable is as always with electrical appliances "folded / rolled" so it is "wavy" in the beginning. This waveform of the cable causes that the first week the whole thing was very shaky and fell down at the smallest touch. Unfortunately, the cable, the cable is more difficult as the charging station itself. Once marked and released to the charging station moves of its own accord over the basin, the following cable. Fast but coordinated movements after getting are not my thing, so I have fixed the holder with double sided tape.
All in all I'm very happy with the brush and with a piece of adhesive tape has the "problem" done with the charging station.
The value would have earned 5 star but for charging station and failure to point out the emptying batteries I have to deduct 1 star.
