Question about Philips Sonicare DiamondClean Smart

I can now answer the question myself, as my Sonicare broke by chance a few days later and I then of course bought a Smart model.

In my opinion, it's not worth it if you still have a working Sonicare without Smart.

The app collects statistics, evaluations and gives recommendations - quite nice but not much more.
You only get the "full" benefit if you have the app open while brushing your teeth, but who does that except for the very first time.
For the synch to work in the background, you have to give the Philips app permanent access to the location - I don't like that, even if they promise not to track it.

Conclusion: Ok but still a lot of room for improvement...
