Hi-end electric toothbrush
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 purchaseTLDR; 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.

Better than Sonic Care
I used Sonic Care for years. After my last Sonic Care brush broke after only a year of use I tried this Oral B brush. This brush works much better. It definitely gets the plaque off a lot better. The app is cool but doesnât always know where in your mouth you are brushing so I just use the 30 second interval vibration in between zones. All in all this is a superior electric toothbrush.

Fantastic Upgrade Over Previous Oral B
Iâve 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 donât 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. Itâs really amazing. Other reviews have called it a gimmick, but I often get distracted when brushing, and I know I donât focus brushing all sections of my teeth, so Iâve longed for something like this. It shows me exactly where Iâm brushing, and it indicates when Iâve 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 itâs in your price range. Given the history of my previous 2 Oral B electric toothbrushes, this should last a long time.

Game Changer for Oral Hygiene â But Battery Life Falls Short
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 Iâd use it long-term, but it proved incredibly helpful in identifying missed areas and improving my brushing technique. While Iâm unsure of the appâs 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 excellentâquick and hassle-free. It took exactly one week from return to replacement.That said, my replacement brush isnât 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!

Using it for a month and so far I really like it. Feels like itâs doing a good job. It makes sure I brush all over and not too strong which is an issue for me. It isnât cheap but I think itâs worth it.
Cliente de Amazon –
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 aquà viene lo peor de todo, su baterÃa, cada 3 dÃas 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 muchÃsimo 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 baterÃa, porque si no es asÃ, cuando ya no funcione compraré de nuevo el phillips, la pila y app es lo que me hace darle solo 2 estrellas,

Desde que el producto llegó, se nota la calidad de los materiales y la organización. Es justo como lo ponen en fotos. La sensación de limpieza es mucho mejor por donde le veas; y consumes menos pasta de dientes por el tamaño del cabezal. Lo único, es que la baterÃa podrÃa durar un poco más de lo que le dura.

Tengo ya 10 años utilizando cepillo dental eléctrico y de todos los que he probado (5), éste, sin duda es el mejor. Es lo máximo porque es el más potente, menos ruidoso y súper eficiente. La carga me ha durado una semana de uso diario. Además, se agradecen todas sus gracias: diferentes modos de cepillado, conexión con app al celular, pantalla (muy bonita) y ¡¡¡estuche/cargador para viaje!!!
