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.

Best Brush Ever
I have been a Sonicare user for several years and I believed it to be the greatest of all tooth brushes. Upon a recent visit to the dentist the hygienist Spoke so highly about the Oral B I just had to give it a try. Since I am a bit of a techie I bought the model with all of the bells and whistles and I do love all of the advanced features, but just speaking of brushing; the Oral B is by far the best tooth brush I have ever tried. I look forward to brushing now because it leaves my mouth feeling like I just left the hygienist chair – that fresh and clean.

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.

Wow!!!
This is really expensive for a toothbrush, but I gotta say itâs worth it!I was an Oral-B user for years and I previously had a Pro4000 model. But it has since made my gums bleed and I decided to go for a toothbrush with âgentlerâ bristles so I switched a bit to Foreo Issa 3. However, that was a bad move on my part. That toothbrush worsened my plaque build up and roughened my teeth enamel, so I thought to go back to Oral-B.Iâm not from the USA so I debates buying this, but it turns out both adaptors included have built-in voltage regulators. So you can use this fine from 100-250volts from your mains, just use a matching adaptor for where you might be.This is a huge upgrade from Pro4000. The bristles for me clean better (I use it at Sensitive Mode) and the pressure indicator is a big help. Like other reviews thought itâs a bit tough to see the timer unless youâre already working your way through your upper back teeth. But this brush reminded me again why I was an Oral-B user in the first place. Really great clean, and when used with Waterpik + a great mouth wash, Iâm sure my next dental appointment will be very positive.A con though is that yes, the battery can be vastly improved. Can lose a chunk of charge with just a single use. And, no, you donât need the app to use this. Just mind the timer.

Producto muy bueno para mantener los dientes y encÃas muy limpios y libres de placa, al principio si te llega a sangrar pero vas agarrando práctica y encuentras la técnica para una limpieza adecuada.

Used this thing for a month now, and to be honest I felt really foolish to spend this much on a toothbrush but it has single handedly for me been worth it. Gums no longer bleed anymore and have gotten a lot better, brushing patterns have gotten a lot better with the help of the app and other features, after I finish I feel like I just got out of a cleaning and my teeth just feel a lot cleaner now, some people this may not be worth it but for me this has 1000% been worth every penny

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!!!
