Cleans great, much better than a classic toothbrush
Fits great in the hand, holds well
Integrated wireless charger in a travel case
Many settings are only available from the app on the mobile phone, without it we have a toothbrush with one factory mode.
The app requires registration and consent to share data - there is a "no, thank you" button next to the consent, but we can't go any further than that.
High application consumption. To transfer data, the app must be running while cleaning (phone with you in the bathroom), app rating on Google Play 2 stars.
"Vegan leather" on a travel case is just a "progressive" name for leather - a nightmare from the days of socialism. They haven't found worse material?

Previous versions without pressure sensors were better, ...if it could at least be turned off, but it can't, mobile app useless, I thought it would logically guide and recognize where you brush your teeth by "sensors" but it's not. For a toothbrush that I bought for almost 10k I expected it to be more flexible and according to my needs and not to have to stick to the manufacturer's fixed settings.
interrupts the cleaning intensity briefly at slight pressure
useless mobile app

lighter and smaller than the previous model I had in this series. very easy to use and one-time setup via the app as well.
the charging stand is unstable. The charging cup of the previous series suited me much better and fortunately it is also usable with this model.
