Very effective toothbrush!
Size: 7 Count (Pack of 1) Color: New Lunar Blue
Excellent toothbrush in a pretty lunar blue color. Includes 6 brush heads. Smart brush heads tell you when they need to be replaced. The smart brush heads clean well - l could really feel the difference. Has an app, but I don't think it's really that necessary if you're already brushing carefully. FYI, Phillips supposedly will send you a free brush head and extend the warranty another 6 months when you register. However, their coupon expired in 2025! ... show more

Treat yourself! I promise you will NOT be disappointed!
Size: 1 Count (Pack of 1) Color: Old Lunar Blue
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. ... show more

Excellent for a never experienced user
Size: 1 Count (Pack of 1) Color: Old Lunar Blue
I was a non-believer in electric brushes. I never thought they would do very good compared to just using a regular toothbrush. I didn’t know what to buy so I figured that I would take a chance and go all out. If I wanted one, I wanted to ensure I got a good one for a good experience of how it should be. And not settling for something cheap that would continue keeping me a non-believer. I love this brush. While I have no experienced other brands or types, I know for sure that it is doing a darn good job of cleaning my teeth. Feels clean, feels good, and does not feel uncomfortable at all. My first experience with it was during travel. The case is excellent and convenient with a USB to charge and can be secured in the case. The standard charger for home use is very nice and the glass is very sturdy (if I break it, it’s because I got careless with it). Battery life seems to be more than enough to go for quite a while without a charge. But that should not be an issue anyway with having 2 ways to charge it. The app itself is quite simple (kind of disappointing between what I expected and what it does). How it works is that the app defines the range of teeth in quadrants. Top left, bottom right, inner, outer, etc. it does not know which tooth you are currently brushing or for that matter, which quadrant you are brushing. It merely knows whether you are brushing the inner or outer part of your teeth (the handle seems to know if the brush is on the inner or outer part of your teeth). So while not what I expected, it’s still effective enough to ensure you have fully brushed all areas of your teeth. But the app cannot determine if you are brushing the left or right side of your mouth. It is expecting that you are following it’s instruction. You don’t need to use the app. But I would recommend starting with it. Because depending on the setting, the handle gives an audible buzz that tells you to switch areas. And if you do not know what or where that means you should go next to brush, you cannot define what it is telling you to do. It even recommends which brush type to use based on your settings. Overall though, my first experience with my first electric brush being this particular brand and model has changed my way of brushing. And unless something goes wrong between now and next few years or so using it, I’m sold on this and do not even need to try another. ... show more

The most AMAZING smart toothbrush!
Size: 1 Count (Pack of 1) Color: Old Lunar Blue
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 ... show more

I have to downgrade my rating
Size: 1 Count (Pack of 1) Color: Old Lunar Blue
This is the nicest toothbrush I’ve ever owned and it should be for the price. The problem is that the high price seems related to its status as a “smart” toothbrush, which it really is not. The app for this device is mediocre at best. This toothbrush is app driven but the app itself could be more flexible. First, sometimes I’m in a rush and I don’t always have time to use the app. When the app is not in use, I feel that the toothbrush should revert to the “traditional” 30 second timer for each quadrant. Second is with the app’s flexibility. I have always brushed the entire top front uppers, then moved to top inner teeth. I then repeated for the bottom teeth. This app forces me to brush six discrete areas. I’m used to it now, but it still annoys me that I can’t brush the way I’m used to. Update: As nearly as I can tell - this is a very effective toothbrush. But... the app, while potentially very useful forces me to brush the same spots over again. I think this might have to do with however the app/brush determines where the brush-head is in your mouth. I’m fairly confident to say that it knows in which quadrant you are, but I think it gets “confused and is not always sure if you are working the inside or outside of that quadrant. My biggest complaint is the availability of brush heads, specifically the T1 tongue brush in black. Mine “expired” and Amazon does not and hasn’t had them in stock for some time. I called Phillips directly and was sent two white (I agreed to that) “dumb” heads that do not connect to either the brush or app. Phillips customer service is awful. Again, I’m sure that this is a fine brush, but you pay a premium for their app and top of the line connected brushes. It is a holistic package, but it falls short if you can’t get replacement brush heads. When this brush goes, I certainly will not be getting this, their top of the line model. I’ll have to knock down my rating for this product. ... show more

Gets your teeth really really clean
Size: 1 Count (Pack of 1) Color: New Rose Gold
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 ... show more

The number different brush settings is fine for those who would use it (I think those ...
Size: 1 Count (Pack of 1) Color: Old Lunar Blue
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. ... show more
