    This was an upgrade from a 3 that I have had for years. I didnt think there would be much of an improvement but wow what a difference. I haven’t bothered with all the features yet but this cleans and is even eaiser to use than the older models.

    Loving this toothbrush! I purchased this one to replace my Phllips. This one is so much better! I love how you can clearly choose the setting from daily clean to sensitivity etc.... it's so cute when after you are done it rewards you with either a smile of a sad face lol. But on a serious note, it does clean my teeth a lot better than it's rival. My teeth look and feel real clean! Love the way it stands on the base and it just looks very cool and modern on my counter top. Gave it a 4 star only bc I'm having an issue with the app. I cant get it to work properly. I'm sure that once I can get it to work I'll be giving it a 5 star.

    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.

    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!

    I used to have the oral b genius 9600 and i thought it was top of the line but when i bought this one i had no wordd for it. This thing is definitely grade A top of the line. If your pockets allow it i advice everyone to get one.

    To be completely honest. The first week of using this thing it is absolutely amazing. After about two or three months, you question if it was worth it. It doesn't seem as powerful anymore, and I wish the app was better. I don't think the extra modes really do anything differently. I think it should be cheaper. You can't pause it if you need to add more toothpaste which is super annoying. The lights are really confusing too after awhile you'll realize it.

    The most sophiscated toothbrush I've ever owned

    Of course the "sophisticated" part is due to the Bluetooth connectivity and the brushing app. The brush and app can tell (for the most part) if you're applying too much pressure and track your brushing (if you're using the guided program). On a few occasions it wouldn't' track properly, but I might chalk that up to an old Samsung S7 or weird connectivity issues with my phone. The travel case doubles as a charger which looks good but haven't traveled (Wuhan virus and all). I'm thinking $100 of the price tag is for the four brush heads (like multi-blade cartridge razors these are the expensive bit).

    Teeth are extra clean. the only negative i have about this tooth brush is that in order for it to docuement how you washed yoru teeth you need to have the phone connected and next to you each wash. I wish it would just automatically connect to wifi or something and send the info to the app vs having to have the app connected to the toothbrush every monring and every night

    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.

    I absolutely love this new toothbrush and the app to tell my that I have fully covered all of my teeth. It has a tongue brushing session as well that is timed for 30 seconds. I would recommend this toothbrush to anyone and may get a similar one for my daughter for Christmas.

    Why did I wait so long to switch to Oral B?

    My dentist told me I was brushing too hard. He told me about electric toothbrushes that would signal when I pressed too hard. I made the switch from my old Sonicare to this new Oral B - iO. I thought it was nuts to spend almost $300 for a toothbrush. Nope! Worth every penny. I’ve never used a round head toothbrush but I feel my teeth are cleaner after brushing. Easier to brush my back teeth. Also, love the colors that indicate red for too hard, green for just right and white for too little pressure. Easy to clean the brush head and the handle. Great purchase!

    The Oral-B-iO Series is a quality product that does all it says it will do. That said, it does take some doing to get completely made aware of all of its features. Documentation is somewhat limited as the product expects the purchaser to go online to discover all of the possibilities. The toothbrush comes in various configurations which also leads to some confusion with the included information. It is rather powerful! I usually brush on a "normal" setting, but I must use the "sensitive" and my wife the "super sensitive".

    Switched from Sonicare to this Oral-B and couldn't be happier. I like the little screen and timer that let's me know when I'm done and shows the time and i also like that it shows red if I'm pushing too hard.
