I put on the highest level the same times, that was very strange and tickled, after about 2 weeks but I have gotten used to all the settings.
By 2 minute runtime I also brush really so long, help 3 pulses that no tooth is forgotten because it really starts to get used to a standard when cleaning.
But the best was my first visit to the dentist. I have never received such good feedback on the state of my teeth cleaning, including tartar situation.
The cleanness feeling after brushing has therefore not deceived, it was confirmed once again also in the oral hygiene of the assistant.
A good investment for the future ...
Deterioration of toothbrushes adheres well within limits - approximately 2 to 2.5 months keeps a. Thus, the costs are in the long term actually not that much higher than with a conventional toothbrush reasonable that needs to be finally changed every month.
Battery life also OK, holds about 2 weeks ...
