The brush has a pleasant design that does not spoil anything. In addition, it comes with a nice travel case, into which the toothbrush can be nicely stowed and, in addition, charged through it. I struggle a bit with the feel when cleaning, even though I have the vibration set on low the oscillating bristles tickle my tongue too much and it's quite uncomfortable - it takes some getting used to. One thing I would criticise about the case is that the head can be placed in it, but only without the protective cover, so this cannot be carried with the brush, it could be useful at times to give the rather expensive head some extra protection. A big minus then deserves the application and actually pairing and synchronization. Occasionally, the app displays an instruction that is replaced by another instruction before the person reads it. The app started to search for the toothbrush that needs to be switched on (by taking it in hand), but before the pairing was completed, the toothbrush went to sleep again, so the app was unable to complete the pairing -> Paired only after a few minutes, when it managed to catch the interval when to take the toothbrush in hand to wake it up, and when exactly to click the button. This could definitely have been done better. The manufacturer states that the app does not need to be on when cleaning, that the cleaning data is stored in the brush and can be synchronized afterwards - which I would like. Unfortunately, very often, in fact most of the time when I finish brushing my teeth and then want to download the data in a few hours, the toothbrush connects, but the app claims that there is no cleaning data. So basically nothing is stored. I think that's a pretty big disadvantage. I don't want to brush my teeth and have to keep my phone on with an app on it so I don't accidentally lose data. The charger is a nice little pancake with some pretty ugly plastic on it. As if it would be a problem to make it nice as one piece to make it look like something.
Guided brushing - helps avoid common brushing mistakes
Practical travel case
Design
The case also serves as a charger
Unsophisticated pairing process
The head can also be stored in the case, but only without the cover
Data transfer between the toothbrush and the app often fails and data is lost
The charger is unnecessarily out of its parts, it could have been made as a nice monoblock.

The app does not allow you to set your own length of time to clean, which in practice means that after two minutes of being on it turns itself off and you are then not able to properly clean all the teeth in your mouth, you have to do two cycles to clean everything and thus you are already the app is completely useless and serves only for some settings of the brush which could certainly be done with the buttons. Because of the fact that you don't make it in one cycle it will scold you for not cleaning everything Even though in the next cycle you finished everything. I don't know why they didn't develop the app with the toothbrush so that I could tell the app when to move to the next quadrant of teeth instead of some stupid timer that doesn't take into account the fact that I'm not that skilled at hand-eye coordination, and the fact that I have very damaged teeth that are complicated to clean. Nothing, too much.
It is a very high quality and effective sonic toothbrush.
It is very portable thanks to the cover
Great to hold (and lightweight)
The application does not allow you to set your own cleaning time

I had been looking into a sonic toothbrush for a long time and I'm glad I finally chose this one. Just a few days and despite the higher price, it will convince you that it was a good investment. Personally, I wouldn't expect to ever be this excited about a toothbrush.

I am satisfied with the brush. Thanks to the app, I have feedback and can improve my cleaning. What is practical is that in addition to the charger, a travel case is included.
The app actually shows the length of cleaning, in twelve segments (individual days and then the average for the week).
In the application, excessive pressure can also be seen retrospectively (again in each of the twelve parts of the mouth).
The anti-scrubbing function is also excellent (a person used to a regular toothbrush simply cleans with an electric one out of habit, which causes scrubbing)
The brush measures 2 minutes of cleaning and switches itself off. Of course, it can be switched on again.
To sync, you need to put your phone very close to the toothbrush and turn on the app.
If the app distinguished individual teeth instead of just segments, it would be even better.

The brush cleans very well. Once connected with the app, there is a choice of modes and together the toothbrush and app then guide the user to clean the teeth evenly and long enough. The price is high, but it matches the quality, often there are discounts of around 20%, so it is worth waiting.

I was hesitant about which el. toothbrush to choose - I've never had one before. I chose intuitively - I call it, "the smart toothbrush". Great satisfaction, many features - and I really use all of them. I don't regret it for a moment🙂Eva Halendová
excellent toothbrush, I paired it with the app on my phone- it informs me of proper brushing- friction, pressure, hold, tooth coverage. It monitors the battery level. gorgeous look, practical beautiful case, charger- for my everything 👍It's my first el. Toothbrush- I chose the newest line- excellent investment. Satisfaction.

If you travel a lot it's probably the only reasonable choice, the rest of the competition has travel cases very clunky or extra adapter which I really refuse to carry, the case is very nice and the ability to connect it to USB-C is very nice. The stand is also very nice, but I would have expected the possibility of at least lightly fixing the charging part in the stand, as it just lies on top of each other and tilts out. As for the data, I was expecting a bit more detailed record, it's actually only about whether you brush your teeth evenly on each surface, you don't learn anything more, which is fine, but after the xth cleaning when you know how to do it, it stops being interesting, and we don't have to talk about the fact that the record of the movement is also not very accurate, sometimes it just doesn't record it properly even though I'm convinced that I washed that part of my mouth perfectly fine. Otherwise, the settings only through the app which I consider an advantage, but everyone must evaluate it for themselves. What I consider a disadvantage are the touch buttons, they do not work perfectly, they are probably very sensitive to the cleanliness of the touch surface, sometimes I turn it on until the fifth time, this is not very successful for me, here I would welcome if I could run the cleaning from the application. I wouldn't buy it for 8299, but if you catch a discount and can buy it for close to the lower model I guess it's cool. Otherwise, I don't see any extra added value except for the travel case, next time I would probably choose something more affordable and "dumber" because this toothbrush is not very smart from my point of view either.
