    This electric toothbrush works great. Once you charge it, it stays charge for quite a while. The toothbrush works in conjunction with the app on your phone.

    I owned several leading brand electric toothbrushes before but this model is by far the best i ever had. Amazing battery life. Strong pulse that cleans deep. I highly recommend this tooth brush, when you think about it, 1 dental procedure will be more than enough to cover the cost, so your saving a dentist visit.

    I purchased this toothbrush because my oral b pro finally gave out after about 6 years so it was time for an upgrade. The sonic care takes some getting used to but after a few uses have noticed cleaner teeth. The pressure sensor is sensitive but again I am used to brushing harder with the oral b. The charging cup is convenient and sleek. The travel case with charger is another convenience as I do travel a lot. So far I am very satisfied with this toothbrush. I cannot comment on the multiple attachments since I have only used 1, but I would definitely recommend this toothbrush. A bit pricey but with 7 brushheads and a tongue scraper I won't have to purchase anymore anytime soon so I felt it justified the price as I am the only person using the toothbrush.

    I think theres alot thats offered to the app, and battery life. Although the app could use some tweaking so you dont need to have the app open in order for it to store data when you brush your teeth. I dont see this being worth it for $300. It definitely replaced my old brush and I'm satisfied with the results.

    It took some getting used to, looking down at an app on my phone while brushing my teeth. The toothbrush gives you sounds and vibrations along with visual cues from the app to let you know where to brush, for how long and at what speeds. Added to the goals that coincide with things such as fresher breath, whiter teeth, etc are toothbrush heads that add a bit of gamification to the process. Pretty neat

    I had an old diamond clean that I had for about 6 years. It was still working, but I wanted to use the app, the tongue cleaner and heard the newer one just works better. After about a month of owning this I can say it works a bit better, but not noticeably better. The app is really neat, but you have to remember to sync it which after awhile I found more tedious than anything. I love this style of toothbrush as I would never go back to manual, but of you're just starting out I'm not sure I would go all the way to this one. I've only ever had diamond cleans so I really dont have much to compare this too other than a manual which just does not work

    What's the most you have spent on a toothbrush? This one is $300 and comes with a bunch of heads that apparently have some sort of RFID in them. Toothbrush keeps track of how long you have used each of them and nags you to buy more when Philips is low on cash. Pro tip, you can use the non RFID heads and they work just fine. Also, the app is built to extract your personal info and tooth brushing behavior and sell it to the highest bidder. So dont get the app.

    My daughter wanted an electric toothbrush for Christmas last year. After much research, I chose this one. The price is costly but for the features it is WELL WORTH the cost!! This toothbrush has all the bells and whistle. You won't be disappointed. She loves the app as it lets her know what areas she needs to concentrate on more.

    I was in need of updating an older electric toothbrush. Swapped over from another brand, and maybe just because it’s brand new, but I feel this one cleans way better than any other I’ve used in the past. The travel case with charger is a great feature to have since I travel a decent bit. The toothbrush looks great as well (yeah, never thought I’d compliment the looks of a toothbrush). I really don’t see myself using the Bluetooth features often or at all but it’s cool I suppose.

    Pricey for sure but you can catch it at a great price when on sale! So please do your due diligence to get the absolute best price, it’s well worth the effort AND every penny!! This toothbrush has a lot of cool features that are truly beneficial for optimal dental/gum health. Having a device with a ton of features you will probably never use is the worst!!! No fear here! It even provides tutorials via your phone/the app which will forever change how you brush your teeth!! Nice variety of custom options/notifications you can add via the app.

    We bought 2 of these (one for me and one for my wife). This is expensive but it is the best electric toothbrush I have ever owned. It comes with several different head for cleaning and whitening teeth and even a brush for cleansing your tongue. You can even attach this to your phone or table and it will let you know how you are brushing and where you need to concentrate. I don't really use that feature but it's there of you are intersted.

    I was hesitant at first because of the price but went ahead anyways as it was the most expensive one in stock. At the end of the day, its an electric toothbrush. Comfort was good and it came with extra brush heads. It had a interesting bluetooth feature that I paired once, but never used. You get the expected clean feeling when done brushing. I would say it was a little pricey but I have nothing bad to say about it, except the price. I'm in Puerto Rico so you get what you can find in stock or wait for slow shipping. I would recommend if you can find it a little cheaper.

    Definitely an upgrade for me... Had some cosmetic dentistry done, so I upgraded my 10 yr old Sonicare to this amazing electric toothbrush! It makes my teeth feel so much cleaner and I brush a lot longer with the app. Love this new upgrade! Pricey but totally worth it!

    I owned a sonicare in the past, then switched to a normal toothbrush for the last several years. Decided i wanted to go rechargeable again. Looked at the Oral B IO9, but after doing some research, i liked with this sonicare model had to offer. Just got it yesterday, so i have used it only twice, but so far so good. Love the app that helps you time your brushing sessions.

    I have initial Sonic care diamond clean for three years. I just like the brushing which to me is better than rotation method of Oral B. This new model which is more bells and whistles but I do like the adjustment of the brushing intensity. I do not care about the Bluetooth function part, though it is a bonus. Since I am using the diamond clean conjunction with a good mouth wash. I already not seeing my dentist for two years which is quite amazing. The only negative thing is the PRICE which is the most expensive toothbrush I ever used and cost more than $250.
