I wonder why the biggest crap has to have an app. soon the toilet paper will have an app. I don't understand and I won't understand. I don't consider the slower charging a disadvantage, it doesn't bother me.
Processing
The attachment holder could have been a bit better designed, but that's about it.

Unfortunately, the toothbrush leaks from the space between the head and the body. I've tried replacing the heads and still the same problem. I'm sorry, but with a toothbrush for nearly 5.000, - I would not have thought that I would encounter this.
The brush flows in the space between the head and the body
very low battery life (about 6 days)

I am satisfied with the brush. It has quite a few "modes" but I personally don't know the difference. After using it, the teeth are really clean to the touch of the tongue. The difference between a manual brush is really noticeable. But the charging time is really long.

The worst thing about this toothbrush is that it runs out of power very quickly. A 100% charge for 6 minutes of daily cleaning lasts for a maximum of 5 days without using a paired phone. Charging is brutally long, from 10% to 100% in about 12h, it's a mess. I recommend keeping the charger permanently on and putting the brush on it after each cleaning. Buy the brush perfectly consider according to the review here or on YouTube
colourful, clear display
enough cleaning functions
connection with mobile phone
quite light compared to sonic brushes
small head = saves paste: D
long charging time
the rapid discharge of the toothbrush, this is downright awful: (
if you switch from sonic to rotary, you'll be pretty much covered in paste, it flies everywhere
slightly more expensive head
