Worst toothbrush ever

  • Stops working after 6 months

It is the worst and most expensive toothbrush I have ever owned. It has broken three times after 6 months. The battery is continuously draining. After 7 hours of charging, I can brush my teeth for 1 minute, then it turns off again.

Great toothbrush, shame about the travel case

  • Compared to the old series, this one is much quieter
  • Beautiful design without edges, where toothpaste and other things accumulate over time
  • Brushing with the app is actually quite fun
  • Rechargeable travel case does not charge

Chosen this one because of the rechargeable travel case. I thought: handy! I spend an average of 6-8 nights per month 'at a hotel', so it is useful if you do not have to take a charger with you... but simply charge your toothbrush in the travel case. Not so: charging has to be done (again) with a plug... so take an extra cord with you in the suitcase. Not a disaster in itself... better than taking the holder / standing charger with you... but more practical would have been a case that you charge at home... like a kind of power bank... and place your toothbrush in it. Furthermore, top brush... and brushing with the app is actually surprisingly fun.
