First off let me say that after growing up in the 90's the thought of spending $300 on a toothbrush is absolutely ridiculous - until I bought one. The day I received it in the mail, I couldn't wait to get it out and use it for the first time. I had never used a toothbrush like this one before. I usually used the cheaper $10.00 battery powered toothbrushes that you throw away once its depleted. The directions recommend you to let it charge for a full 24 hours prior to using it - however in my case I had already thrown my toothbrush in the trash, and the excitement of the product forced me to use it immediately. When I opened up the package, I was quite surprised of the quality of not only the packing, but the classy display of the contents and the quality of the materials. I picked the toothbrush up - Wow! Never thought I'd be saying this, but "What a beautiful toothbrush" is exactly what I said. The different brush heads are packaged nicely in their separate "baggies". I got the charging base and glass cup out of the packaging, and set it up like the directions say. I set my toothbrush in it and voila! The brush beeps/vibrates twice to let me know it is charging. The battery indicator blinks when the unit is charging. Just like the description says, you get several brush heads: Whitening, Clean/Deep Clean, Gum Care, and one tongue brush. Each brush head is marked on the front of the neck which one it is (C - For Clean) (W - for whitening) and (G - for gum care). If you still aren't sure you can always just place the brush head on the toothbrush and it'll "magically" tell you which one you're planning to use. Another neat thing I noticed is each brush head (that comes in the package) has a microchip, so not only does the toothbrush know which one you're using, it also knows the best intensity and vibration pattern to use which cooresponds with each head. Granted you can change it up anytime you like during the process (brush cycle prior to brushing, intensity while you're brushing), but I thought it was an ingenious idea for it to be this smart. I got the app downloaded, set up my profile, and was ready to brush. I picked the toothbrush up out of the glass - immediately it lights up. I place the "Clean" brush head on it, and the app automatically switches to the "clean" mode and opens up the brush screen - all without me lifting a finger (granted this only works if the app is already open prior to picking up the brush or turning it on). So I turn it on, the app starts telling me the parts of my mouth to brush, and I go to work. The feeling of using this toothbrush vs what I was used to definitely was an awkward feeling - yet it was quite pleasant. I finish the cycle, and then the app proceeds to tell me areas of my mouth I didn't brush as good. It says "Turn on your brush to touch up". I push the Botton and brush exactly where it tells me to. Once the cycle is finished it tells me I did a fabulous job. It reminds me to rinse, floss, and use mouthwash. I've been using this toothbrush for almost a week now and I can already say I'm in love with this thing. My teeth feel as if I've just left the dentist's office. They're already several shades whiter. I'm in love! I will never own anything else other than this toothbrush.

I decided to buy an expensive toothbrush after reading all of the things that it included. I had a Philips Sonicare before, but after many years it died. This toothbrush is very expensive but worth every penny! I now have a little “competition” with myself to finish all of the tasks that my sonic toothbrush app has me do twice a day. It keeps me on track asking if I have flossed, rinsed and scraped my tongue (it’s asks this after I have brushed my teeth as “reminders”). I love that it prompts when to move to the next section. I REALLY love that I can see on the app where I haven’t cleaned enough in one section and has me go back to clean that area. My teeth have had significant improvement in just 1 week of ownership and using it twice a day. I use the Clean brush head in the morning and use the White+ brush head in the evening. Tongue scraping brush head twice a day. The toothbrush design is sleek. I love the travel case and it was recently used on a vacation. The only “downside” was that the travel case included space for two brush heads but not the tongue scraper too. Given the toothbrush app has you floss, brush, rinse and scrape twice a day, if going on vacation, the travel case should have enough space for 3 brush heads. One of the goals Philips Sonicare has you set (if you want) is to have a whiter smile thus using a different brush head then the normal Clean mode and needing space for 3 brush heads. I have a teeth cleaning at my dentist today and I’m interested to see if I get a better report card on this visit than previous visits. Haha

I have used Sonicare Brushes for many years. I liked my older one, but I thought maybe a new one would be even better. This one made the old one seem like a basic toothbrush. If you have not upgraded in a few years, getting this brush can feel like a game changer. I recall that with my first Sonicare brush, there was a period of adjustment while I felt the brush gave me a strange sensation. With my second, it was not significantly stronger, so I did not notice a period of adjustment. This brush is significantly more powerful. Even though I was used to a Sonicare brush, there was a significant period of adjustment. It took almost 2 weeks to get used to it. I have been using the Deep Clean + setting. My teeth are getting cleaner and whiter, my gums are improving. Those promises are true. While this brush has a Tongue Cleaning setting, I did not feel that the features of this brush were truly necessary for this purpose. Also, I did not feel like swapping brush heads, each time I brushed, just to clean my tongue. I elected to put the tongue cleaning head on my old brush and just use that for this cleaning purpose. I suppose if I travel, I would just bring the new diamond clean brush for both purposes. Now for the not quite so good. The connection between the brush and the app is not all that stable. I cannot tell if this is the brush, the app or my phone. For deep clean, you need to do 2x 2 minute sessions to complete the clean. Slightly more than 50% of the time, the app registers the first cycle, but fails to transition to the second cycle to complete the cleaning session. On the second 2 minute session, it lets you know you only did half the cleaning, and prompts you to perform another 2 minute session to finish. This is VERY frustrating, especially when it happens more than once a day. Sometimes (about 3 times a week), the phone and brush refuses to connect. The app suggests that you turn BlueTooth off and then on to establish a connection. This has NEVER worked. I find the only solution that does work is to take 5 minutes to reboot my phone, and let everything start back up again. I find myself pondering if it is really important to me to reboot my phone just to brush my teeth. Also that 5 minute delay can be very impactful to a busy routine. Sonicare, if you are reading this, I do feel you can do better. Sonicare seems to have a strange model/pricing scheme. they have a basic brush, next tier, they add something you want. Then next tier, they add something else you want, but take the first thing away. If you want multiple additional features, you quickly find yourself shopping for a brush that is significantly more expensive than what you were originally looking at. I suppose it is good for their profit, but shopping for a brush can be an exercise in frustration. Summary: Pros -Does it's job really well -Comes with a travel case, and provides USB Charging for the brush, so you don't need to take the stand -Does an excelent job coaching you to improve technique -Coaches you to brush 2x a day, floss etc. All those things your dentist nags you to do, but you forget once you get home Cons -Connection issues with app -Expensive -Hard to find a brush with all the features that are important to you

This Phillips is a game changer. I have used Phillips for 30 years and enjoy the long battery life, the quality brush heads, the ease of use, and the travel ability even without the charger (never needed in 9 day trip). This 9700 comes with multiple brush heads and the base recognizes each brush head for setting. The app leads the user to complete each brushing with a mouth diagram while the base and app warn if too much pressure or scrubbing occurs. It is not noisy, keeps a record of daily brushing, flossing and rinsing. It is multifunctional, even connecting to my Apple Health. The only drawback it not having the UV brush heads cleaner as in past systems.

I’ve already lost most of my teeth due to medications and genetics. I’m trying to keep my remaining teeth as healthy as possible while still being gentle but thorough on my very expensive implants. This is one of the best Sonic toothbrushes I’ve ever owned. It does exactly what I need it to, doesn’t make my gums bleed like others have, and has so many more features that make it a worthwhile purchase. The charger is cute/stylish while still being useful by adding a glass cup to rinse your mouth with. The case is not just sleek and gorgeous, but is high quality and even charges via a USB port that is safely tucked away. No need to bring a bulky charger with me anymore. Now for the reason I chose this one: (it wasn’t just the nice color) it has an app that shows you where you need to focus to get a better clean and how well you are doing. These replacement heads are a bit more expensive, but after paying so much for my implants, I find this to be well worth it. I’m shown how long I should brush which sections, if I’m missing an area in my mouth, if I’m brushing too hard. Over all, if you care about your teeth and don’t want to end up with a mouth full of cavities and fillings or worse: dentures, invest in this toothbrush.

I've been using these toothbrushes for years, but quality continues to decline and I'm done being a customer after this latest round of disappointment. The only reason I've kept buying them is because when they do work they are nice, and I've made excuses for the quality and longevity because they've been dropped a couple times and I've attributed some of the premature failure to these accidents. However, way too many negative reviews about units not lasting, breaking right out of the box, all the same things I've experienced. I bought two new replacements for my wife and I. Right out of the box, the white one made a strange buzzing noise and then a humming sound with no pulsionic action. Doesn't matter what setting it's on or the intensity, it just hums. It was charged overnight, no change. The second one, while it works, did not come with any of the toothbrushes that it was supposed to have. Instead, 4 random toothbrushes with a "w" on them. In the pictures, you can see the variety of toothbrushes that came for the white one, then you can see what came for the black one, and also a picture of the box of what should have come. In addition, if you look close at the pictures, there appears to be water stains and residue on both of these toothbrushes. Seems worse on the dark blue one. I think these were used, or refurbished, although they came in what appeared sealed boxes and sold by and shipped from amazon.com. Believe all the negative reviews. These are not the products they used to be, and Philips is not the company it used to be. At this point, I'm not even bothering with customer service or an exchange. I'm returning.

I've used two older versions of Sonicare toothbrushes in the past and so this is my 3rd one. Why Sonicare as opposed to the competition? I prefer a larger brush head. Here's my cursory review of the flagship Sonicare model that comes bundled with all the extras: The Toothbrush: It works as expected. The number different brush settings is fine for those who would use it (I think those who are prone to be a bit more OCD would use all the settings), though I imagine a good 90% of the rest would just keep it on one setting for most of the time. The handle has a good weight to it, fits well in the hand, and generally brushes pretty darn well! The indicator light that blinks when you are applying too much pressure while brushing is at the end other end of the handle and therefore you'll never see it unless you're directly in front of the mirror. It would have been better if it made an audible sound in addition to the blinking lights. The bundle The premium that you'd pay to buy the 9700 model is the travel case, the extra brush heads, and the training app. Now, I bought this model specifically because I was interested in the training app. So I'll write a bit about that here. It trains you on the basics on how to brush your teeth. It may be that you've been doing it somewhat incorrectly all your life and now here's your chance to have an app monitor your performance- how cool is that! Well, I used it and find that the app does help you with the basics of how long you should brush and which areas you may want to provide more brush coverage. These two factors alone should be enough to offset some of the other things that the app doesn't do quite as well in, right? Well, the app rather new and has enough bugs and other quirky things that make it rather annoying to use for more than just a week or so. In fact, I stopped using the app after about 10 days. I'm sure they will improve the app but for now, I'd hazard a guess and assume that most users will not continue using the app for more than just a few weeks at most. I hope they will improve the app as there's real promise it what it can potentially do. But for now, it has enough design and functional flaws that make it appear more like it's a beta release rather than a product I paid a premium for. I'm sure Philips will continue to improve the app so that it's more usable. The travel charger This was one of the other reasons I paid a premium to purchase this model. However, I must say that the Philips design team must have been asleep when they came up with the design for the charger. A travel charger is meant to be portable and lightweight. This monstrosity weighs three times more than it needs to, is super-bulky, and on top of that, the innards are totally closed in cheap plastic. So a product you'll put in your mouth that gets wet, you're supposed to then stick in a totally enclosed piece of heavy plastic and carry it with you while you travel- just how hygienic is that?? It has a built in charger and as of now, I'd rather carry around the equally poorly designed metal ring base to charge the unit while I travel. Neither of the two options are ideal of course and therefore I hope Philips will reconsider redesigning the terrible travel charger. Would I buy this product again? The answer is yes! I'm certain that Philips will continue to improve the app to make it more usable. Maybe with the next version, they willl have worked out the issues to make it more usable and useful for people to use for more than a week. Also, I hope they come out with a decent travel charging case that is 1) hygientic 2) lightweight 3) not bulky. But for now, it's still the best electric toothbrush around. 5 stars for the toothbrush and -1 star for the poorly designed travel charger and the beta version of the brushing app.

Some 5 years ago, I went to the dentist one day and discovered I had a lot of cavities all of a sudden. After having the cavities corrected and receiving fillings in numerous teeth, I decided to embark on a journey and do everything I could to ensure that I would prevent getting cavities in the future. I had been brushing at least twice a day, but I had not been flossing regularly or doing anything else. I started flossing and using fluoride mouthwash after my routine. One thing I kept putting off was buying an electric toothbrush. I had read conflicting information about whether or not it made a difference. All through this time span, I had been using Oral-B Pulsar vibrating manual toothbrushes. I could not conceive how a Sonicare toothbrush would provide THAT much of a difference. After all, I was used to having a really clean mouth every night and morning with my flossing, brushing and rinsing routine I had developed. For years I couldn't justify the expense of buying a toothbrush that costs astronomically more than what I had. After years of debating it back and forth, I finally decided to make the plunge and see what the top of the line model could do. All I can say is that after a week of owning the Sonicare 9700 Diamondclean Smart, all my skepticism and assumptions turned out to be wrong. The results from this brush are simply incredible. Many reviewers have said this, but I'll say it again. Consider how clean your teeth feel after going to the dentist, then think about what it would feel like if there was a notch ABOVE that. This is literally how clean your teeth feel EVERY TIME you use this toothbrush. I'm completely blown away by how good of a job it does. I'm kicking myself for not buying a Sonicare toothbrush sooner. After using this brush just once, my teeth feel glossy in a way that I didn't think was possible. The biggest difference I've noticed is that the facets of my teeth are clean in a way that simply isn't possible to achieve with a manual toothbrush. I didn't know teeth could feel this smooth. If guided properly, the 9700 will polish and remove plaque from all the little nooks and crannies on, in-between and around your teeth. Your gum-line is stimulated and feel "tighter' around your teeth because they are being cleaned so well next to your teeth. It does all of this and with much less effort than a manual brush. Remember, this is after 1 WEEK, of use. Additionally, the 9700 is extraordinary at teaching you how to get the most out of it. The companion smartphone app is comprehensive and can help motivate some folks with goal selection and other wizardry while you brush. In all honesty, this isn't totally necessary, but it's cool that it can do it. The pressure sensor is a great feature and gives me peace of mind that I'm not damaging my gums or enamel with this powerful mechanical device. You might be surprised about how hard you were brushing before versus what is actually appropriate. The inductive charging feature in the glass is convenient. Just make sure you don't break it. There is a secondary dock you can use if that were to happen, though. Many reviewers have complained about not having a place to store brushes; however, they are packaged in plastic bags, so I'm not too concerned. This likely isn't an issue for me because I am not sharing the brush with anyone else, nor am I swapping out different head types in my routine. Your mileage may vary depending on your priorities. I'm eager to see how this brush holds up and what my dentist thinks in a few months. If you've never used an electric toothbrush before, don't wait years like I did. The cost is well worth it.
