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.

If you're debating between the Oral-B iO Series 6 and Series 9, I get it—I was in your shoes not too long ago! As someone who travels frequently for work, I invested in both, hoping to streamline my packing routine. I thought I’d just be dealing with a few tweaks here and there, but wow, was I wrong. First, let’s talk brushing performance. Both models use Oral-B's "magnetic iO technology," which combines oscillating-rotating and micro-vibrations for an experience that feels more like ultrasonic brushing than the older Oral-B series. After each session, I’m left with that fresh-from-the-dentist smoothness, and yes, both models deliver equally in that department. If the actual brushing is what matters most to you, the Series 6 holds up well. But once you start looking at the extras, the Series 9 really starts to shine. Let's talk about the charging setup. The Series 6 has a basic charger—functional, but nothing to write home about. In contrast, the Series 9’s charger feels like it could double as a paperweight in a windstorm; it’s sturdy and, dare I say, elegant. And for those constantly on the go, here’s where the Series 9 really scores big: its case isn’t just a case; it's practically a mini power station! The travel case for the Series 6 feels flimsy, like something you’d get in a happy meal, but the Series 9’s case could probably survive a fall down a mountain (though I’m not volunteering to test that). Battery life is where the Series 9 once again pulls ahead. I can usually go about two weeks without recharging with both models, but the extended battery life with the Series 9 means I could probably escape into the wilderness and brush my teeth for a month with power to spare. (Hello, camper toothbrush!) And let’s get to the tracking tech, my fellow data nerds. The Series 6 offers decent tracking with six zones, which is enough to keep tabs on each part of your mouth. But the Series 9? We're talking 16 zones of tracking, folks. This means you’re not just getting feedback on the upper and lower quadrants but the front, back, sides, and—let’s be honest—probably nooks and crannies I didn’t even know existed. The 16-zone tracking is almost like having a dental assistant saying, “You missed a spot… and another one.” If you’re someone who thrives on that level of accountability, the Series 9 is your holy grail. Yes, the iO Series 9 is significantly more expensive than the Series 6, and if you’re mostly after a good brush, the Series 6 will serve you well. But if you're looking for a tech-packed marvel with all the trimmings—like precise brushing analytics and top-notch travel accessories—the Series 9 is worth the investment. So which one am I tossing into my suitcase? The Series 9. Because sometimes, your teeth deserve the VIP treatment.

Overall Satisfaction: I give the Oral-B iO Series 9 a solid 5. This toothbrush is amazing and well worth the higher cost compared to other series. Main Purpose: I purchased this toothbrush to maintain optimal dental health and minimize the need for extensive dental procedures. Ease of Use: The toothbrush is excellent, and you can even turn on the phone to track your performance. It offers awards for meeting specific goals, some of which can be challenging to achieve. Performance: The Series 9 comes with additional sensors and a flat magnetic mount for convenient charging. While the battery drains quickly, it's not an issue for short 2-3 minute sessions. Features: The ability to visually track cleaning habits is a standout feature. With multiple modes available, I typically use sensitive, whitening, or daily settings. Durability: The toothbrush is very durable, and despite the quick battery drain, it's not problematic for regular use. Value for Money: Although expensive, the toothbrush pays for itself when considering the savings on dental bills, primarily limited to cleanings. Comparisons: Compared to other Oral-B models, the Series 9 is more advanced, with the phone app being the most significant difference. It provides detailed information about brushing habits and areas that need improvement. Pros: Maintain Oral Health: Keep your teeth clean and healthy with advanced features. App Integration: Track your brushing habits and receive feedback on the app. Charging Options: Charge the toothbrush using the magnetic mount or the convenient travel case with an attached cable. Cons: Lack of Apple Watch Compatibility: It would be more convenient if the toothbrush worked with the Apple Watch, eliminating the need to pull out the phone for information. Additional Tips: For a clean toothbrush and to avoid hardened toothpaste, use the travel charger instead of the magnetic mount. Cleaning the head after each use and washing it with water is also recommended. Recommendation: If you're looking for a top-notch toothbrush that not only ensures oral health but also provides insightful data through a dedicated app, the Oral-B iO Series 9 is worth the investment.

I actually purchased the io 9 series on Amazon almost a month ago. I'm not happy I purchased it day's before it went on sale. It's whatever.. Honestly I have to say this toothbrush is absolutely no joke and worth every dollar I paid. The io series is great I went with the io9 series because it comes with 4 brush heads that's good for around a year or more depending on how you use them . Also the lcd screen Honestly not necessary but I love it.. Most important the performance. This toothbrush cleans better than my dentist has ... My teeth get whiter on every use even while I'm using mouth freshener paste. I can only imagine if I try out some heavy grit whitner paste. Also I'm using it on daily clean not the highest level. It's an amazing toothbrush. If the battery dies it has a 2 year warranty or you can just buy a better 14500 battery Oral-B built this unit to be easy to service. As far as mold building up that's not happening with me. I use warm water to rinse out the brush head and main unit. I almost didn't purchase this because of people talking about mold build up! Smh . Honestly rinse it off as you would any tooth brush and dry it off and also let it air out & charge in a dry area. Please do not stick sharp things like picks in the top of the brush handle. There is a rubber seal that protects water from getting into the electronics and if you poke at it black stuff will come out because the seal is made out of black rubber! I will update this review if there are any issue's. If this is all your seeing know I'm a very happy customer and it's working 💪! I do not like I paid much more than the current sale price is but it's whatever...

After using the product for about a year it started manifesting all sorts of problems. One of the problems is as other people mentioned, the issue with the battery. The unit will show 95% charge and suddenly shows 0% charge and stops. After you put in back to charge for 3 minutes, it is again at 20% and then it jumps itself to 75% etc. One other issue is while you are brushing the teeth, the unit will simply stop and start to reboot itself or stop and refuse to restart until after sometime. Still, the unit can turn on and off on itself. I though there were ghosts in my bathroom turning on and off the brush, lol. As for the software in general, I also had all sorts of issues. After I explained the issue to Oral B, their customer service is extremely good ; no complaints here. They sent me a replacement toothbrush and also sent me a box to send them the old toothbrush and they paid for shipping and everything. One of the best customer service experiences I can say. I was excited. Unfortunately, the new toothbrush IO9 they sent me started developing the exact similar problems after only 3-4 months. At least the one I sent them took me about a year before to start showing problems. I was so disappointed because this is not a cheap toothbrush. I spent about $300 for it. I googled issues with IO toothbrushes and noticed that I wasn’t the only one facing those exact issues. I was relieved it is not because of ghosts in my bathroom I was having those issues. This time i decided I won’t waste my time calling customer support again about the second unit they sent me. I accepted the loss and decided to move on. I bought another OralB but a non IO series. The Genius series. I never had any issues with it.

Loved this toothbrush, didn’t use the app. Just found it gave me the best cleaning and most options. I have special needs, which it helped solve. 2021-2026 with a replaced battery last fall. Now it’s finally done and I’m thinking about getting a new one. Price is ridiculous for a toothbrush and for replacement heads. Twice a day use for years. Only get it if you need it.

This electric toothbrush is excellent. It cleans my teeth thoroughly and reaches areas that a manual brush can’t. The vibration is strong yet gentle on the gums, making brushing comfortable. The battery lasts a long time and charges quickly. The design is ergonomic and easy to hold, and the brush heads are easy to replace. My teeth feel much cleaner and my mouth feels fresher after every use. Highly satisfied with this purchase and would definitely recommend it.

This is really expensive for a toothbrush, but I gotta say it’s 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 ‘gentler’ 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. I’m 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 it’s a bit tough to see the timer unless you’re 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, I’m 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 don’t need the app to use this. Just mind the timer.
