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...

This is LOVE! Compared to a significantly weaker electric toothbrush, which I thought was something, this blows it away! Yes, it is a tad expensive, but it's a virtual little computer that helps those pearly whites shine! The handle has a circular ring at the top, just below where the brush is inserted. This ring changes color as you brush: blue for not applying enough pressure, green for the exact amount of pressure, and red for overdoing it and potentially damaging your gums. It also has different selections, displayed on the handle, for enhanced brushing, daily brushing, sensitive pressure, and whitening. I LOVE this toothbrush! Five Stars easily ...

The media could not be loaded. 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.

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.
