The toothbrush cleans really thoroughly and stops you from "scrubbing" your teeth. The cleaning intensity has 3 levels. The application is very functional and clear. One head should last 3 months.
The toothbrush teaches users how to brush their teeth
Connection to smartphone is easy, app is Czech
The travel charging case is great
The toothbrush does not fit into the travel case with the head attached, it is stored separately under the body of the toothbrush

I upgraded from an older model, so far I don't regret it, it cleans better, but the apps don't bring much and the battery lasts less, the smart features seem to me to be only on paper
Great cleaning that is the main reason to buy this tab
Short battery life compared to older models (only 14 days)
Cleaning mapping doesn't work very well
The problem zones seem to me to clean exactly the same

I purchased this toothbrush as a replacement for an older model and the generational leap is huge. I hope it will be qualitative, only time will tell.

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.

We have a family of toothbrushes from Philips in the top Prestige series. 5 in total. Each of them has been in complaint, some even 3 times. Great for brushing teeth when they work, but otherwise they are unreliable junk. They either stop working completely, shut down during cleaning, or start making strange noises and vibrating badly. A warning would be the high claimability on Alza for the unlimited (non-image) edition. If you were hesitant, like I used to be, I would definitely go for the Oral-B iO Series 10, there are no such problems with those. As soon as Philips toothbrushes go out of warranty, we buy Oral-B. Unfortunately, Philips service is even worse. Complaints always take almost a whole month and usually the service only changes the motors, they didn't give us new pieces, so you literally have a new toothbrush that someone immediately tinkered with.

Cleans teeth beautifully
Top quality workmanship
A nice bonus is the rechargeable travel case, which acts as a power bank for the toothbrush
100% satisfaction!

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.
