    This is a great product, very expensive but pretty good for what you paid for. I have receded gums and I have seen notable changes on my them. I was not certain to purchase this item, but so far it has improved my oral health. If you are looking for this product to improve your oral health such as your gums, buy it. I took a start because it is an expensive product.

    After almost a month of ownership, this is a very big improvement compared to the Oral B genius X. The cleaning process is very effective. The brush are a lot softer and the little display is useful to check the remaining time. Battery life is okay, about a week or so. Now the only thing that will truely matter is the lifespan of this product. These guys usually last only about 2 years so I’ll update this review in the event it changes!

    This toothbrush has made a huge difference in how clean my teeth feel after brushing, it truly feels like I went to the dentist for a cleaning! The app works great and defiantly helps you learn how to brush better. Battery life is also great!

    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.

    For whatever reason, I am geeky about buying high end electric toothbrushes. I decided to try this Oral B model after using a high end model made by another company. I really prefer the Oral B brush heads and the smart technology and app associated with this model are nothing short of amazing. I come away every time I use it feeling like a hygienist has just cleaned my teeth.

    I had a Sonicare that died recently. My denist recommend Oral B. I was nervous to purchase this as I was not sure if I would like the smaller brush head. If this is a concern of yours do not worry. I feel my teeth are way cleaner with this brush head. I can tell my brushing is more concentrated on each tooth with the rotating brush action vs the straight vibration on my Sonicare. I’m very happy with this toothbrush and i’ll be interested to hear what my dentist has to say ar my next appointment.

    If only they didn’t change a couple old features

    This is a really good electric toothbrush. Furthermore, I think it’s actually important to note that in a day and age where everything is going overboard with smart connectivity and millions of options and settings, this actually doesn’t do that. It’s as if someone high up said, “You can put modern features in, but at the end of the day, don’t forget it’s just a toothbrush.” And I appreciate that they didn’t try pander with useless gimmicks. This does, however, have 2 faults that are making me on the fence about returning. The first is the brush heads. I have this on the extra sensitive setting, and even got the sensitive brush heads. But it’s still not soft. Feels at least like a medium in a manual toothbrush. And my old model from at least 5 years ago had a replacement head that was very soft. So that came in as a real bummer. The other thing is also a feature in older ones that aren’t in this. I know it can be personal preference. But in the old one, the vibration would immediately stop entirely when you put too much pressure on it, and immediately resume once corrected. This keeps going, but does notify you by changing the ring at the top of the handle red. The old way was more of an interruption, and possibly a bit more annoying. But the annoyance of it is what helped curb the habit of brushing too hard. For those where that’s a big problem, the old way helped curb that habit pretty quickly. Overall, I would say you don’t need to spring for one this expensive, considering it doesn’t have any features that are a true wow factor. And is a bit limiting in areas.

    Packed with features, great battery life, and reliably reminds you to change the brush heads. The mobile app is a great extension to this toothbrush. Allowing for even more in depth control and features.

    Oral-B iQ series 9 toothbrush works great with the Oral-B phone app to show where you need to spend more time brushing and areas that you have spent enough time on. Quick charge, sleek design, easy to hold while brushing your teeth. The price is really high, the only drawback.
