For me, a very big disappointment. We had toothbrushes almost 7 years old, also Philips Sonicare. I figured I'd pay extra and get "the best". Rather, it's a step (if not several steps) backwards from the "old" ones. The old ones had 3 diodes indicating battery charge. One knew at first glance. Nothing here. One diode. The old ones had mode switching. Nothing here. All through the app. Basic things like modes and battery I would like even without the app. As for the noise level, I wanted to change the brushes because the original ones seemed "already" noisy. Compared to these, they're quiet. The body of the toothbrush does not have a hole at the bottom, so it does not fit into the charging case that we have with the UV sanitiser. Charging case disaster. It opens in the bag when you run or put the bag on the ground. The head can only be there without the cover. Charging is also not indicated in any way. I would have expected a pointer as well. We are trying to give the brushes a chance, but the longer I use them, the more I "miss" the old quality ones. About the only plus is the heads, but they fit the old ones too, so I could have bought the heads and been happy. I don't even comment on the connections and cleaning indicators in the app. That doesn't work as much as it works. I'd like to switch modes, but the toothbrush won't connect.
perhaps the only plus are the heads, but they come separately on the older ones.
They look nice, but that's useless to me considering the cons: )
worse than 6 years old models
noisy compared to the old ones
no charge indicators
a useless case. Opens, no indication of toothbrush charge, head only without cover
switching modes only via the app
the connection doesn't work rather than works

The card itself is great. However, since it is sold together with the application (based on the selection of all kinds of cleaning, which cannot be selected on the card), it will go on claim. The app is a disaster! After removing the card from the docking station and switching on cleaning, the application does not start cleaning. After I have cleaned the whole floor it catches on, but it does not save the cleaning record. Even with repeated reloading it is the same error. At the beginning everything worked fine, but after a week of use it's getting worse (it started on one side, then the middle and now it's doing the whole palate... I know my teeth are cleaned, but it bothers me that somewhere in the app I look like a slob who doesn't have cleaned teeth and it's glowing golden.

I am literally thrilled and immediately bought a second one for my daughter. Your teeth are cleaned in a way they never are with a regular toothbrush, polished, clean, and I have the impression that even tartar comes down over time. Of course, it does not completely clean the spaces between the teeth, but there are other tools for that. About the app, I've read comments that you have to keep looking at the app while cleaning, you don't have to! The app just teaches you how to clean, then you know how to do it and don't need to look at it. The toothbrush vibrates at each tooth segment after 30 sec to alert you to move on to the next one. And then it remembers your cleaning, so you can synchronise it at other times than when you're cleaning. So you don't have to keep looking at your mobile as some reviews say. I recommend him wherever I go, so I recommend him here as well: ) Plus, I love the pale blue pearl color.
Luxury teeth cleaning
Application
It looks beautiful
perhaps only that the modes can not be switched directly on the brush, but must be from the app

I'm a bit disappointed that the OralB iO 10 is honestly a better equipped device and in some ways better thought out. I used to have a cheap OralB, but after that experience I chose Philips for two reasons: there are no stupid holes in the head of the toothbrush where saliva flows into and it can't be cleaned, and secondly because brushing is not just about physically scraping your teeth as I used to think. Philips suits me better.
I find sonic cleaning better than just "scraping" with OralB, and I honestly feel better about the cleaning.
BASIC: no holes in the brush head where saliva flows and stinks
On the outside, the toothbrush gives a better impression than the OralB iO 10
Background app sync. it doesn't sync, I don't know why. I have to do it by hand.
The app is pretty slow
Replacement heads are not cheap no
Compared to OralB iO 10 less equipped (display, clock puck)
Switching between modes requires an app
