Not great so far
[This review was collected as part of a promotion.] I liked my e series toothbrush that I used for over 10 years better than this one. It doesn't seem to have the power and intensity that I expexcted.

[This review was collected as part of a promotion.] I like the diamond clean smart 9700 because of the numerous settings options that covers any concerns or needs that I may have in my dental care. I also love the durable charging travel case. I would have given this 5 stars, but my last diamond clean only lasted 7 months and the stem that held the brush just broke. Was not dropped or damaged in any way. I bought another one, but at this price I expect it to last longer and if it does not, this is the last one I will ever buy.

Great product
[This review was collected as part of a promotion.] I have been a longtime fan of all things Phillips. My latest purchase of the Diamond Clean toothbrush has taken me to a new level of appreciation. It’s a little pricey but it’s worth every cent. Every time I use it I feel like I’ve just been to the dentist for a cleaning.

Sonicare Toothbrush 20X
This is my forth Sonicare electric toothbrush. I like the fact that this toothbrush cleans 20x better than manual brushing. My last Sonicare toothbrush cleaned 7x better than manual brushing. I like the fact that there are 2 separate push buttons; one for selecting type of brushing & another for on off mode. My toothbrush came with a number of extra toothbrush’s. Presently I’m using the one that is probably the most expensive. Please see photo I took. I really like this brush head! I rinse the handle of my toothbrush thoroughly after every brushing. I haven’t set up my toothbrush with my phone app yet. I hope this toothbrush last a minimum of 5 years. That’s how long my last Sonicare toothbrush lasted. I do recommend using a Sonicare toothbrush; your teeth are whiter, fewer cavities, less tarter buildup, overall better hygiene cleaning of your teeth. My hygienist always says my teeth look like “pearls”. I’m 78 years old and I can’t live without my Sonicare toothbrush!

Horrible quality control. Tho Customer sat superb
I have been using this same model for more than a decade, but I have to purchase a NEW ONE roughly every year as the same issue recurs -- the motor gets louder as the metal bar in the main body gets looser and eventually the brush no longer works. This last one only worked for 3 months before same thing occurred.

Do not buy - faulty battery
Just laid my second one of these toothbrushes to rest after a little over a year of working. It's a nice toothbrush when it's working, but one day it just stops functioning for no reason. This is the same thing that's now happened to me twice. The first time it happened Sonicare did replace the handle and I got another year of use, but now this one has also died. There's clearly something wrong with this product and the company has no other solution than a 30% off discount with free brush head for your money and time. DO NOT BUY!

Does not last more than 1 to 2 years
We have been Sonicare toothbrush users in the household for a long time. I’m getting fed up them and no way I’ll invest that much money again. It will not last past 1-2 years (especially close to warranty expiration). Trust me this happened to us twice. My son even used one of these and yes electric brushes are better than regular ones. Both of our brushes stopped functioning and mine sometimes vibrates / turns on out of blue on its own. It is not worth investing into it. We might go to $50 one and that is a max we would spend on Sonicare.

A great replacement for any of the competitors!
[This review was collected as part of a promotion.] I was using a top-of-the-line competitor toothbrush from Oral-B, but the DiamondClean Smart 9700 HX9957 is so much better for my particular mouth. I like the DiamonClean brush head shape, as it allows me to get into corners that the competitor brush head does not!

Best Clean from an Electric Toothbrush
[This review was collected as part of a promotion.] So far I have absolutely loved this toothbrush. It gives me an amazing clean and makes my teeth feel so refreshed. The app makes it easy to ensure I get the best clean and helps me monitor my usage for the best results. The sleek, quiet design makes for a convenient way to have great oral health without a hassle.

Pretty nice!
[This review was collected as part of a promotion.] This is a decent toothbrush & nice, but I don’t think it cleans my teeth as well as my regular manual toothbrush. The battery does last a very long time though, it’s quiet, and the app works amazing in correlation with your movements. I do love the technology that they put into it, though, you can tell a lot of thought and attention to detail is there.

Redefining
[This review was collected as part of a promotion.] I was ecstatic to receive this device and I am so happy to share that it has gone beyond meeting all of my expectations. The DiamondClean is more than a toothbrush, with a user friendly app it provides an experience that encourages improvement and wellness by providing feedback on your brushing. There are 5 different modes and 3 intensities to choose from, which makes this toothbrush incredibly versatile in meeting your needs and preferences. This package includes 6 brush heads, 2 tongue brushes, a usb charging travel case, a charging glass and stand. You can feel the quality when handling all items, especially the toothbrush itself. The battery life so far has been excellent, I charged it for a full 24 hours after taking it out of the box almost 3 weeks ago and that charge is still going strong. I am so happy with my experience.

Changed the game!
[This review was collected as part of a promotion.] I never thought I would be an electric toothbrush girlie but here I am! The Philips Sonicare Diamond Clean Smart brush has been a game changer for me. It comes with multiple brush heads to fit your specific oral care needs. Come with a glass cup, chargers, and actual directions that are helpful. I highly recommend downloaded the app for the brush as well, it helped explain everything this brush really can do for your oral health!

Best Smart Toothbrush on the Market
[This review was collected as part of a promotion.] This toothbrush is not only extremely aesthetically pleasing but works wonderfully! I love the multiple brush heads, cleaning options, and tongue cleaner. The toothbrush senses the pressure and will light up to help you adjust your brushing. It also has an app for your phone to help guide you as you clean your teeth so you don’t miss anything. This Smart brush makes it so easy to ensure you teeth are clean!

This will teach you to brush properly
[This review was collected as part of a promotion.] This tooth brush leaves my teeth feeling smooth and sparkly every time. The app is very easy to use and has shown me I was probably being too rough on my teeth. The battery lasts longer than my last electric toothbrush so worrying it will die in the middle of brushing hasn’t been a problem. I love the different heads as well as the tongue brush.
