    I love this tooth brush comes with a different modes and extra sensative mode works best with my teeth i no longer get built up tarter on my gum line. I recommend you get this when on sale. The 9 series is a must if you want a good electric tooth brush the 10 series is better but more spendy.

    Powerful new motor can be unforgiving on gums

    I will start by saying i’ve been a long time Oral-B electric brush user for many years and have gone through a few of these which normally last a long time. I had the Genius 8000 Oral-B last and that was my favorite due to its rubberized grip - which was much better than this new series 9 super slick grip. Now on to the brushing performance- I was initially BLOWN AWAY with the series 9 new motor as my teeth never felt so clean- so i immediately realized they changed this to use vibrations and spinning somehow. Whatever they did it was POWERFUL. so for the next 2 weeks or so i was originally brushing for 4 minutes but this brush always knows exactly how long you brush with its timer display- that is amazing on this one. so i immediately backed off to 2 minutes. Here’s where it gets interesting- after about 2 weeks - i noticed my gums started hurting and i could see they were receeding- as in they were starting to show less of my gums - weird right! so i remembered thinking this brush seems so much more powerful than my last,, so i changed the program from Daily Clean to Sensitive- and wow- HUGE difference- for me Sensitive is almost perfect and it doesn’t shred my gums the way Daily Clean did- but- after about a week, i did notice my teeth didn’t feel as clean even though my gums felt happier. so every now & then i need to go back to Daily Clean for a better clean even though i cannot stay on that setting as it shreds my gums too much. Overall this is a great brush - but it’s far from perfect as Braun needs to understand their new motor technology better. I have seen another electric brush which automatically adjusts the pressure based on how you brush, and i wish i would have learned about that before i got this one. But my previous oral b was perfect. now with the series 9 i have to manually switch modes to prevent it from hurting my gums.

    Best Electric Toothbrush Yet

    The IO Series 9 works well for the iOS app and helps me to keep my teeth cleaner with guidance through 16 zones. Just had my teeth cleaned and got an A+ from the hygienist. Batter life is good and I like the charger built into the travel case. Best Electric Toothbrush Yet for me.

    Works great. The app works well in tracking the areas you cover with your brush in real time. The powerful motor within the brush runs relatively quitely. Im enjoying this product.

    This toothbrush is amazing. Helps control the amount of pressure applied to the gums and teeth, it tracks the brushing time and it cleans teeth that you can feel & see the difference. I feel that It’s on the expensive side but it does a good job.

    I was the owner of the Phillips Sonicare, but after having used this roughly 2 times, I LOVE the tech this has. The integration with the phone app to really analyze brushing habits is fantastic! The brush itself feels premium and really does its job while being packed with features! Highly recommend.

    Amazing tooth brush, is it pricey? yes absolutely it is, is it worth it? Yes absolutely it is. I had a cheaper model Oral B and I thought it was cleaning my teeth just fine until I tried this one and wow so much cleaner feeling!

    This is the best toothbrush ever I have had a lot of electric toothbrush’s but this one is awesome. It has a much thicker head on it so it does a better job and you don’t feel like it is going to break while brushing and it tells you when you are brushing to hard which is nice. It is Bluetooth so you can track how often and how long you brush comes with a nice travel case.

    Absolutely! You really need to try this. I thought my old toothbrush from the same brand was just fine and that I only needed to change the attachments every so often. Boy, was I wrong! This one leaves your teeth feeling so sparkly clean—it’s such a game-changer!

    Expensive but I think it's worth it. My teeth actually feel cleaner and I've found myself actually enjoying brush my teeth and look forward to it. But maybe I'm convincing myself that because of how much it cost me. If you don't mind spending the money, it is worth it. Plus, I wanted the travel charger case because I always hated having to drag a charger with me when I travel, and I always found it odd that more companies don't make a good travel case for their toothbrushes.

    Not only is this toothbrush sleek but it has multiple settings. I have sensitive gums so I’m generally using the sensitive setting. I used a sonic are for probably 15 years. This is so much better. My teeth actually feel clean afterwards but it has a timer that keeps me true to 2 minutes every time I brush my teeth. It’s much easier to clean as well, there are holes in the head so you can really clean out the residue after a wash, the sonic are was hard to keep clean with how it is built. The charging portal is easier to keep clean as well. It also comes with a portable charging case which is GREAT because I travel for work. Overall 10 out of 5. I wish I had invested in this sooner.

    A worthy upgrade over the Oral-B Triumph Pro.

    TL;DR The iO-9 is a worthy upgrade over the Oral-B Triumph Pro. Being a current Oral-B Triumph Pro owner, I was skeptical about upgrading to the iO-9. I didn’t think there would be enough improvement, since the Triumph Pro isn’t that old and seemingly performed well. When the iO-9 went on sale, I became an owner. Having just used the Triumph Pro, I followed up with the iO-9, and I could immediately feel a difference. Like all the other reviews state, just like leaving the dentist office. The app on your phone becomes more useful now, in that it displays which quadrant of your mouth you’re brushing and down to the level where on your teeth: the inner, top or outer of the teeth with the goal of 100% coverage. The Triumph Pro basically just functions as a timer. Personally, I find the iO-9 to create less of a mess and rinses much more thoroughly than the Triumph Pro. I never make the rookie mistake of turning it on or off outside my mouth. The battery life isn’t as long, but it’s a non-issue for me. When the battery gets to 25%, it has the same performance. The Triumph Pro slowed down. The iO-9 is lighter and significantly quieter too, and the charging light isn’t nearly as bright which is bonus.
