The toothbrush provides comfortable cleaning and is quieter than the previous model, while its ergonomic design ensures it's easy to handle. However, from my perspective, the premium features seem insufficiently effective for their cost. A single touch button would be ideal for a one-time setup of the brush in the app, but unfortunately, after about 3–5 uses, my device's cleaning intensity drops to the minimum, which requires reconnecting to the app and setting it up all over again. The cleaning guidance feature only monitors the tilt of the brush and determines whether you are cleaning the inner or outer side of your teeth, without detecting its precise position in the mouth. Very often, even this basic guidance doesn't work, so the brush not only doesn't know where it is, but not even how it's tilted. The accompanying app is quite confusing and it often takes a long time for it to find and connect to the brush. The app repeatedly failed to synchronise with the brush, which required non-standard solutions that are not mentioned in the official app support. All in all, considering the purchase price, I'm not very satisfied with the product.
Quieter than the last model
The touch button doesn't trap dirt.
Charges faster than the previous model
Multiple cleaning programmes
The cleaning guidance mostly doesn't work
Without regular connection to the app, the brush forgets the cleaning intensity setting.
The synchronisation of the brush with the app sometimes plays up.
The toothbrush doesn't recognise where it is in the mouth.

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
