    • Oral-B iO Series 6 is Solid Brush, but the iO Series 9 is in a Class of Its Own
Color: Aquamarine Size: 4 Piece Set Style: iO9 Power Handle

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. ... show more

    • Best toothbrush around
Color: Rosequartz Size: 1 Count (Pack of 1) Style: iO9 Power Handle
I absolutely love this toothbrush. I love the settings and having 30 second increments of cleaning each section of your mouth. It does a great job cleaning your teeth and leaving your mouth happy and clean. It’s definitely worth the price as it lasts longer than other toothbrushes out there. Worth the buy! ... show more

    • Great quality vitamins and very reliable for kids
Color: Blackonyx Size: 1 Count (Pack of 1) Style: iO9 Power Handle
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. ... show more

    • Very bad product. Avoid the IO series. Go for the Genius or Pro Series
Color: Blackonyx Size: 1 Count (Pack of 1) Style: iO9 Power Handle
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. ... show more
