The Oral-B iO Series 9 was my first electric toothbrush, and I can confidently say it transformed my oral hygiene. I thought I had been doing a good job with manual brushing, turns out, I was wrong. The "app" integration was another surprise. I initially doubted I’d use it long-term, but it proved incredibly helpful in identifying missed areas and improving my brushing technique. While I’m unsure of the app’s absolute precision, my results have been noticeable, even my dental hygienist commented on the improvement! Now for the downside: battery life. Oral-B advertises over two weeks of battery life with two 2-minute sessions per day, but in reality, that was not even close. My unit barely lasted a week at first and eventually struggled to hold a charge for even two days. Fortunately, the warranty process was excellent—quick and hassle-free. It took exactly one week from return to replacement. That said, my replacement brush isn’t much better in terms of battery life, even after just a month of use. While this is frustrating, the improvements to my dental health outweigh the drawback, and I highly recommend this toothbrush despite the battery issue. If you get one, register it immediately to take advantage of the two-year warranty as you may need it!

Here's my look at it: This toothbrush is for lazy people who just don't like morning routines. Powered toothbrushes clean so much better compared to manual ones! This one has so much power my gums bled at the beginning. What I like: - long handle, can reach places you wouldn't reach with short toothbrush - timer that shows how long do you have to brush for - battery lasts (took it on a trip with no charger, 1 week daily use - no problem, can probably last even longer) - changing this battery is possible - bottom unscrews, no glue/adhesive/buy a new unit bs! - thank you, Braun engineers - relatively impact resistant. I dropped it 3 times on a hard tile floor, and it survived the fall. You shouldn't test it, because it depends which way it falls and on what surface, but mine is fine. - has an app. This app allows you to track what teeth exactly you have brushed, but I found it excessive, while it is a 'wow' technology for someone who are crazily obsessed with oral hygiene, I am just brushing without it now. Which one to pick? Honestly, I'd go with io7 if you don't care about bells and whistles, especially if the price is tasty. If it costs around $200, go with this one. What I don't like: - I wish manufacturer let me position toothbrush vertically in the case (make a small indentation for it to stand), instead of dismantling it every time when I travel - heads for it are kinda expensive - can be expensive, not a regular dollar store purchase TLDR; Hi-end electric toothbrush for lazy people who would want a quality teeth cleaning with some of the features that I found excessive, but otherwise built robust and does its job well.

I have enjoyed using this toothbrush since the day I got it. In a few months it will be 3 years since I purchased it, and have had no issues with battery life. I keep it on the charger at all times except when traveling. (This is my third Oral B electric toothbrush and I've never had a battery issue of any kind.) The travel case is great. One thing to be aware of is that the case itself doesn't re-charge the toothbrush--you need to have the brush in the case and have the charger charging the case. The 2 minute brushing reminder (which vibrates at 30 second intervals until you're finished) works very well--it definitely keeps me brushing longer than I would otherwise! I don't bother with the app, although I probably should! Also, doesn't vibrate your brains in your head like the Sonicare does. Good job, Oral B!

I’ve been using Oral B electric toothbrushes for many years. My second one just got glitchy a few weeks ago, so I decided to get a new one. Oral-B is by far the superior brand, so I only had to choose which model to get. I went with the IO9 because, for the features I need, want, and like, it was the best value. The key feature that made me select it over a lower priced model was the included charging travel case. I don’t travel often, but it will be very handy when I do, especially when going overseas. I was also interested in the app that connects to the toothbrush to track brushing. It’s really amazing. Other reviews have called it a gimmick, but I often get distracted when brushing, and I know I don’t focus brushing all sections of my teeth, so I’ve longed for something like this. It shows me exactly where I’m brushing, and it indicates when I’ve spent the correct amount of time with the correct pressure. This toothbrush is so much quieter than my last one, and my teeth feel cleaner. The shape of the toothbrush shaft is much sleeker than the last and more natural to hold. It is costly, but it would be a valuable investment in your oral health if you choose it. I highly recommend if it’s in your price range. Given the history of my previous 2 Oral B electric toothbrushes, this should last a long time.

EL producto tiene buena calidad en su fabricación. Su aplicación es deficiente, todo el tiempo tiene recomendaciones de cepillado que jamás quitan y aparecen cada vez que te cepillas (después de un mes es un martirio verla , y después de un año bueno.....), Para el cepillado cambia constantemente donde realmente te cepillas, *no funciona* eso hace que trates de arreglartelas para mover el cepillo como loco, para darle a la parte donde salen las indicaciones de esta app, pero aquí viene lo peor de todo, su batería, cada 3 días hay que cargarlo, no puedes salir ni un fin de semana, porque se acaba la pila, antes usaba el sonicare de Phillips y la pila si dura muchísimo más. La diferencia del cepillado entre estas dos marca no hace mucha diferencia, considero que es mejor el Oral B, pero no por mucho, ojalá tengan más cuidado con la app y batería, porque si no es así, cuando ya no funcione compraré de nuevo el phillips, la pila y app es lo que me hace darle solo 2 estrellas,

Bought it last year as a Christmas gift and the battery is now done …. It did not last a great deal! We all use oral b for years, this is the first time battery life is so short

I got this a few weeks ago. I couldn’t get it anywhere in Australia so had to order from us with us cables. It’s a really nice toothbrush you do feel super clean after if you’ve brushed correctly. I have come from the rose gold sonic care (another expensive toothbrush) - this is great but having to have my open and app open all the time is annoying. Look great product only thing is I don’t think it’s worth the nearly AUD500 I paid. But I’d rather have clean teeth snd have good oral hygiene then visit the dentist. So it’s worth it I get. Still can’t get five stars I feel something is missing still for this price can’t figure it out but something. Happy brushing!

Feels quite different to previous electric brushes, very clean finish definitely worth it.

Unfortunately the display stopped working after 6 weeks. Very disappointed. Fortunately the local Singapore Braun Service Centre replaced the toothbrush under warranty. However, unfortunately it was replaced with the only available handle color of Black, and not the great pink handle color that we originally purchased.
