    The toothbrush leaves our teeth feeling very clean and smooth. The app helps improve our brushing technique and we love the different brushing options and customization. The charging travel case also comes in very handy! The price tag is a little high.

    I’ve been using the oral b electric toothbrushes for years and they are definitely a step above the rest. Makes me and my dentist happy. My only issue with this model is the battery life. The older models last for a month while this one needs charged every week. At this price point, that is disappointing.

    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.

    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.

    I love this electric toothbrush. I like the built in timer, the pressure warning when you are brushing too hard and the different setting. It has a charging carry case for travels as well.

    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.

    Expensive but worth it

    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.

    My Teeth Have Never Felt Smoother

    I recently upgraded to the iO Series 9 and the difference is night and day. The first thing I noticed is how quiet it is compared to older Oral-B models—it’s more of a hum than a rattle. My teeth feel "dentist-visit clean" every single time I use it.

    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.

    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.

    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.

    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.
