What do users say? AI-generated summary

Users primarily appreciate the effective cleaning and good battery life, with the overall feedback being very positive. The three modes and timer make daily brushing easier, and several users report a noticeable upgrade from more basic models. However, the Bluetooth connection and app do not always work smoothly, while some users mention declining battery performance or difficulty charging.

    Excellent, convenient case, exceptional cleaning, very powerful! It is important to also use the correct brush heads, of course. As for the battery, I don't know, as I always have it plugged in.

    The Oral-B Smart 4 4000 is a value for money toothbrush. It may not belong to the new generation of Oral-B, but it manages to do the job and do it well. The three programs it has are quite good and have good application in several cases. Its battery has a long duration and performs excellently. The only problem I encountered was with the application, which freezes and connects either after a while or not at all. Of course, this could be due to my phone, which, however, does not have problems with other applications.

    I replaced an older oral b that I had. The difference in battery is amazing. And the power of the toothbrush is the same. I haven't bothered with connecting it to an app, etc. Useless in my opinion.

    I have had it for a year now and I use it daily, three times. The characteristics that are stated are really true. If there is something I would like to improve, it would be the charging time, and because I travel, I don't like having to take this base that takes up space in my suitcase.

    I am satisfied, I give it 4 stars because there are much more expensive ones on the market that will do something extra. However, this specific one suits me. The mobile application now doesn't offer anything, it's more of a marketing trick for me, since the toothbrush already notifies you when to change the side you are cleaning anyway, even without the application...

    This review is about the colour: White

    After using it for about 20 months, I have to note that this particular toothbrush cleans the teeth quite satisfactorily, but the battery performance has dropped significantly. Specifically, after a year and a half, it requires charging every two days, with brushing twice a day. At least in my case, this happened.

    It does a good job, connects easily to the smartphone, the reverse countdown for proper brushing every quarter is very useful... the only negative thing at first that I would mention is that it makes a bit of noise, however after brushing it feels like you just came back from a dentist cleaning. No comparison to the simple entry-level models of the same company... the 3 brushing modes (regular, for sensitive teeth - gums, and whitening) are also useful.

    This review is about the colour: White

    With a cost of 50 euros, I save both the dentist and the daily hassle compared to a classic toothbrush, and I have a truly much cleaner smile.

    - From the first uses, I felt like I had gone for a cleaning at the dentist.
    - At first, I was bleeding from my gums, but over time it healed (due to plaque removal).
    - It has 3 speeds, which I especially needed at the beginning when I had sensitive teeth.
    - I use the app on my phone, and all of this puts me in a mindset to be more focused on my daily brushing.

    I definitely recommend it!
    (Especially compared to a simple, more economical Oral B).

    This review is about the colour: White

    I have had it for about a week and I am very satisfied compared to the cheaper models of the same brand. The battery is the biggest upgrade as with one charge I have lasted the whole week instead of every 3 days like the other one needed. Now, the majority of the settings and the 3 programs it has do a better job in cleaning, so you can buy it without hesitation, the best for this price.

    This review is about the colour: White

    Years of electric toothbrush user, I decided to buy this device for its capabilities. I have had it for 6 months and I can say that it is value for money. 14-day battery life with a lithium-ion battery, something that cheaper models do not have. 3 modes for cleaning and Bluetooth connection to the mobile phone where it keeps a record. The only thing left is to see how long the battery will last. The cheaper models lasted me 1.5 years of use with 2 brushings per day before the battery performance started to decline. It is worth the money

    Very good device. The only problem is the built-in battery, which is very difficult to replace if it breaks

    Very good cleaning, no comparison with the previous and cheaper model of the company.

  • Excellent, convenient case, exceptional cleaning, very powerful! It is important to also use the correct brush heads, of course. As for the battery, I don't know, as I always have it plugged in.

  • The Oral-B Smart 4 4000 is a value for money toothbrush. It may not belong to the new generation of Oral-B, but it manages to do the job and do it well. The three programs it has are quite good and have good application in several cases. Its battery has a long duration and performs excellently. The only problem I encountered was with the application, which freezes and connects either after a while or not at all. Of course, this could be due to my phone, which, however, does not have problems with other applications.

  • I replaced an older oral b that I had. The difference in battery is amazing. And the power of the toothbrush is the same. I haven't bothered with connecting it to an app, etc. Useless in my opinion.

  • I have had it for a year now and I use it daily, three times. The characteristics that are stated are really true. If there is something I would like to improve, it would be the charging time, and because I travel, I don't like having to take this base that takes up space in my suitcase.
