    Great toothbrush - if your a gadget lover

    If your a gadget person and don’t mind spending the $$$ for this it’s well worth the money. As far as a toothbrush, it does an excellent job of cleaning. The settings for the modes of brush are great. I have sensitive teeth so the these brushes sometimes can be to vigorous, not this one. The sensitive setting works great. Setup was easy and the brush connects to the phone every time. I could only find two very small issues and I do mean very small: 1. When unpacking the toothbrush you have to take everything out of the box to get to the instructions and I mean everything. Even the cardboard insert that holds the pieces in place - a bit of a pain. 2. The 3D tooth location is not always accurate from top to bottom teeth - so when you brush, you’ll get a report saying you didn’t spend enough time on that portion of you mouth. Like I said really small things. Bottom line is if you have an extra 300 laying around and want a really cool toy the will help with your oral health then this is the toothbrush for you. As for me I was impressed enough that I will definitely purchase a Oral-B toothbrush next time I need one although it will probably be one of the less expensive models.

    I am such a picky person when it comes to my oral hygiene. I am always looking for that "just had my teeth cleaned by the hygienist feeling". I FINALLY FOUND A TOOTHBRUSH THAT GIVES ME THAT FEEL!!!!! I love the how it seamlessly works with the Oral-B app! I have used this brush like crazy and I am crazy in love with it! I will list the pro's and con's to help you make a decision. PRO: -Extreme Clean, Fast Charge, Charging Case, Multiple settings and heads, Streamlines with the application to help you achieve the best oral hygiene, the design is there. Who doesn't love 7 different brushing modes! I just absolutely love this toothbrush! CON: Avoid touching those gums, this brush is a beast when you are using the "intense" mode. The toothbrush "Wakes Up" when it is moved, I wish you could just turn it off. it was a lot of battery if you are moving it. I honestly can say this brush gives you that clean dentist feel and result, from your home. You can't beat it. I bow to you Oral-B!

    Just Like The Dentist

    I forgot how much I missed using an electronic toothbrush. As others have mentioned there are several different modes of brushing which you can easily set to your preference. Set up was very simple and the app is quite easy to follow. The only reason I am not giving 5 stars is because in order to fully appreciate where you are brushing as the toothbrush sends this to the app in real time, I really do not like having to look at my phone while brushing my teeth. Taking my phone with me every time I brush my teeth isn't something I would want to do and I would lose interest. But again that's just my honest personal opinion. Now don't get me wrong, using this brush makes you feel like you had your teeth professionally cleaned at the dentist. It does a great job of cleaning. As I mentioned it has different cleaning levels and I appreciate the sensitivity setting as it is perfect for my gums. All in all this is a solid unit and I would definitely recommend it.

    Great Toothbrush

    First off, and most importantly, this is a great toothbrush, all smart features and bells and whistles aside. It gets the job done and leaves your teeth feeling clean and fresh. Now, on to all the fun stuff and what you pay extra for. I have to admit, I was a bit skeptical and expected the extra stuff to be a bit gimmicky. I was pleasantly surprised at how useful the smart phone connectivity is. The app can tell you which areas of your mouth you are missing while you brush, and even which areas you are brushing too hard. This can be very useful when starting a new brushing routine. For instance, I recently had some periodontal work done and have been paying attention more intricately to my brushing routine. If I had this brush at the time, it would have been so useful. I could've seen exactly where I was missing, and even in real time seen that I didn't quite have 100% coverage yet. I don't see myself using the app forever, but it's nice to improve your brushing habits. The biggest issue I have had with it is that I don't always remember to bring my phone with me, especially in the morning when I am half awake. In conclusion, this is a great toothbrush that really gets the job done. The extra features actually work really well, as advertised, and if it is something you are looking for in a toothbrush, you will not be disappointed.

    I’ve used Oral B products before, and would already recommend them. After using iO Series 9, I know that I’m getting the best care for my teeth! The application that is used to setup on mobile devices is very simple to use. You download it, and it will automatically find the toothbrush via Bluetooth. Once it’s paired you will be able to start brushes from your device. It starts with a normal brush, then tongue, then floss and rinse. While your brushing though there is a visual on your phone indicating where at in your mouth that you are brushing. It starts off ligh blue then ends up bright white. There are animations to make it look like your teeth are sparkling! The toothbrush charges via a magnetic stand. The kit comes with 4 brush heads as well so you have plenty to start off with. As well as a carrying case that you can actually charge by itself! This whole kit is awesome, and I would definitely recommend it to anyone looking for something more than a toothbrush.

    Outstanding cleaning. Don't use the app, but the on-device settings and cleaning seem to work very well. Not sure how much better this is than the cheaper models (if it's worth the extra money or not).

    Messy, only worked 7 months, bad CS

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I had earlier oral-b elecric brushes and they lasted 10 years with minor loss in battery fade. Was excitef to upgrade to this series 9, at $300. Was thrilled, but quicky learned that needed to brush directly over sink or it would spray and drip toothpaste eveywhere. I was adjusting. Then 5 months in, it would die after 20 seconds (battery said 96% when started). I thought it was a fluke. Then it happened every time. I called oral b, they said if i mail it in, they can try to service it. I’d be without a toothbrush for 6 weeks. They dont just send out a replacement. They dont trust you that the product is defective. They dont trust youll send it back. They offered send me a manual $5 toothbrush to use temporarily. The toothbrush is a lemon. Many others have same issue with this model. Oral-b doesnt offer to replace. I would avoid this model. Im still looking for a replacement but scared to buy another high end oral-b product.

    stupid brush head design

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    it's a really bad design that the brush head comes with a hole or even two. water and toothpaste trapped in the head becomes black filthy suff over time. Seriously why Oral-B does this? for better sale of heads? pushing customers to Philip?
