Excellent. The new toothbrushes of the IO series have nothing to do with the previous ones we have known for so many years.
Very good cleaning, huge battery life compared to the old mechanical ones we were used to for so many years.
It was truly a pleasant surprise. The series is on another level now. You won't go back to the old ones.
I'm not sure if you need more features than the series 3 for much more money. The IO 3 toothbrush turned out to be excellent.

Very good, huge difference in the feeling after washing, without many unnecessary functions, good battery autonomy, a bit slow charging, deep cleaning, worth the 62 euros I bought it for.

The previous 2 Oral B toothbrushes broke after 2 years. They were more expensive models and I decided to get something more economical without bluetooth etc. that "drain" the batteries prematurely. It is quieter than the previous models, with a wider brush. The case is very cheap compared to the cases of more expensive models.
Overall, I am satisfied for now. Do not buy the expensive models, they are not worth it because they do not last long and there is no option to replace the battery.

Compared to a simple Oral B, the cleaning is clearly better.
Negative is that there is no indication of which program is selected

First time using an electric toothbrush and I was shocked with this one, it removed tartar in 10 days!!! It's more than worth its money!!!

I have had it for almost 4 months and it is very good! It cleans very well, I personally use the attachments for sensitive gums and my gums don’t bleed, and I also set the intensity for sensitive gums. The battery so far definitely lasts 3 weeks with use twice a day. The case is very practical.

Excellent product, it has nothing to do with the old ones that were rotary and transferred germs to the mouth. It works more smoothly and more effectively. The most economical one is this one, around €50, it only comes with one spare part as a gift. I got it on offer, which gave you two more as a gift, that is, a package of two. It does not have a screen and does not connect to Bluetooth; you have to go for model 6, which costs around €100, double the price, but I don't think there is any significant difference except that it connects to a program on your mobile

The best electric toothbrush, it cleans thoroughly, leaves nothing behind, it's like getting a cleaning at the dentist

It's worth it, it's very powerful, does a good job, deeply cleans the gums, it really scrubs them to clean them and that's how it should be. Nothing like the cheap electric ones. I don't understand why a toothbrush should have 10 different models, is it a smartphone?

excellent choice at a very good price. cleans teeth very well and gently, while notifying you when the toothbrush pressure is higher than desired.

Much better compared to the previous model. I also went for cleaning after 1 year and the dentist told me it was as if I had done it recently. She attributed it to the toothbrush and the medicinal toothpaste I use

it definitely makes a difference, it is very good, but I don't think you need to spend 100-200-300 etc. I believe they all clean more or less the same. I'm not an expert of course, I might be wrong. I remove one star only because they have an issue with the app, I can't connect from my phone, it doesn't detect it

Simply excellent!
Battery life (as new) is very long!
A month(!) has passed since the first charge, and it still works at 100%!
I received it on October 1st.
(I use it for 2 minutes - a complete brushing)

And generally, it is very good in everything, it has no flaw. Clean after each use, and that's it.
I highly recommend it.

It discharges quickly, you need to press the on-off button, the programs are not visible like in the genius model I have for years which has separate buttons depending on the function you choose, it does not have a travel case nor a protective cap for the brush which is important in my opinion

Much better than the older one that had a battery failure. Better cleaning, quieter operation, and much greater autonomy.

After a recommendation from a friend who is a dentist, it really feels like you just had a professional cleaning! I had the basic Oral B from the supermarket, which is 2D, not 3D like this one. The higher series (4,5,6,7,8,9) have Bluetooth and other unnecessary features. With this one, you get the job done and you don't need to spend a fortune, great choice! I wish it just had some kind of cover

For 9 years I had simpler Oral B models
And the truth is that the difference is huge…
You don't need to go for more expensive models, now if you want to connect it to your phone, what can I say

Excellent! It replaced an older orab b I had, from a decade ago. This one is much stronger and you immediately feel the cleaning it provides.
